/hormones/PMSing, or is just how I am?

I was on the shot for 3 years and I haven't had my period since I started the shot. Now I just started the combination pill about 3 weeks ago and since then can identify three or four specific days where I basically had a mental breakdown, felt extremely anxious, irritable, depressed, couldn't stop crying. I can't tell if they were caused by the pill because I already suffer from anxiety and depression, and I just can't remember if these "breakdowns" were a regular thing before I started the pill and I was just not paying as much attention to them. Since I started the pill I've kept a log of my symptoms including mood, so I know the exact days where my mood was really bad. Before I started the pill, I hadn't kept a log of my mood. **How can I tell if the pill is wreaking havoc on my mood, which is already somewhat unstable due to preexisting anxiety and depression?**

I have heard a lot of people say that birth control affects their mood, but I just saw an article/study that said there isn't any evidence that birth control can affect your mood... I don't know what to believe.A pocket calculator, which is pretty unusual for normal peoples' usage, is the model "Programmer" from Texas Instruments: This calculator, which appeared on the market in 1977 and which was produced several years, is only capable of the four standard calculations, but is also able to calculate in the hexadecimal and octal number system. And with a few hints, you can also work with binary numbers.
Those calculators were't suitable for normal households, but were mainly used by software developers and computer programmers, which had to calculate bit by bit because of the power-less computers with very tiny memories that time.
As interesting as the TI Programmer is by its special calculations, as boring is it in its technical construction. More about that later.
The plastic case of the TI Programmer consists of two case parts, which are tied together only by a few stong plastic barbs. No screw, nothing expensive at all. Simple, but efficient.
The upper case half has got a red inlay on its upper third. This inlay is partially tilted and covers the LED display. Beyond the display, there's the embossed "Texas Instruments" logo. The whole inlay is surrounded by a silver colored frame.
The rest of the calculator is used from the keyboard and its aluminium cover plate. This brown plate is printed in white and blue.
The keyboard is simple constructed: There are fourty(!) keys, internally covered by a foam (which does not last that line), which press on the key plates and give an acustically and haptically feedback. The keys hardly bounce, but for some reasons, they are pretty slow to use.
This calculator does not have an On/Off switch, but is instead activated and switched off by two keys. This way, TI could save a real switch, which needed a stronger case and was prone to misfunctioning.
The inner construction of the calcualtor was quite revolutionary for 1977, but on the same time very boring, too. Except the keyboard and the mainboard, which only contains one chip and the LED stick, there are no further parts used. No resistors, no capacitors, no transformers, no forther ICs.
TI really perfectionized the "Calculator On A Chip".
The very bright LED display with its strong magnifying bubbles was up-to-date that time.
Due to the small size of the light emitting fields (they had to keep the power consumption as low as possible), the tiny digits had to be enlarged massively by strong bubbles. The disadvantages of that technics were, that the display seems to lay deep down in the case and even worse, it is not possible to look at it sideways or at an tilting angle.
The display is driven as usual in a multiplexing way, but here, the multiplexing frequency seems to be quite suboptimal since the display flickers noticeably.
To save even more power, after 30 seconds without use interaction, the display is switched off and only a moving dot reminds the user, that the calculator is still powered on. The last value can be brought back into the display by pressing the "=" key.
After about five minutes without any entries, the calculator switches off automatically.
The TI-Programmer uses the "Calculator On A Chip" ZA0675NL CPU. In the calculator described here, this chip was made in week 19, 1979 in Singapore.
The construction of that calculator is identical to the TI-30; they only differ by the used CPU (which probably only differs by the firmware).
The normal calculating capabilities of the TI Programmer are not very spectacular: In the normal mode, it can only do the four standard calculations, up to four brackets and has got a simple memory with a summary function.
In the hexadecimal- and octal more, there are a number of further calculating operations such as the 1 complement, AND, OR, XOR and bitwise shifting. The hexadecimal mode is indicated by a double apostrophe; the octal mode by a simple apostrophe.
The calculation range goes up to 99999999, ocal to 37777777 (8388607 decimal = 2^23-1) and hexadecimal to 7FFFFFFF (134217727 decimal = 2^27-1).
The memory function is realized by three keys; there's no display indicator: "STO" stores the displayed number, with "RCL", the memory store can be recalled into display, and with "SUM", the current displayed number is added to the memory contents.
As most calculators of Texas Instruments, the TI-Programmer also contains a so-called "Batterypack", here of the type BP-8, which consists of two rechargable AA cells, who generate the neccessiary voltage of 9V DC. The AA cells are recharged by an external transformer, which delivers 8.5V AC. During the recharge, the calculator can be used, of course.
Unfortunately, the integrated accus leak after a while, since the calculator uses a little bit of electricity, even when it is switched off.
Such a leaked AA cell pair can be replaced by an expert.
The consumption of the calculators on its 9V connector is 16µA (=0.15mW), when switched off, is 12mA (=0.1W) when only one zero is shown, is 44mA (=0.4W), when all digits are on and on the power-saving mode, it still consumes 7.3mA (=0.065W).
The 0.4W were undercutted by calculators with VFD display, and those displays were also larger and readable from all positions. But the drawback of them were, that they needed a number of external parts, which were not possible on a "Calculator On A Chip" design.
The TI-Programmer is a technical rather boring, but due to its unusual functions rare and interesting pocket calculator. Such a model is an enrichment of a collection.A quote from a catalogue:

1982. This year Cycles Peugeot celebrates its 100th year in the manufacture of its prestigious line of bicycles. That is a proud record of accomplishment for Peugeot – and strong proof of our hard-earned reputation for building the most responsive and durable lightweight bicycles in the world.

Two of our newest 12-speed bicycles, the P8 and PH10, are manufactured through a process developed exclusively by Peugeot engineers. To begin with, we make our own tubing called “CARBOLITE 103.” This is a special, thin-walled tubing made from a composition in carbon steel unique to Peugeot. This tubing combines strength and resilience and produces the unusual durability of our bicycles.

2. Learn the alphabet ASAP, learn to read, it's actually super easy, it takes 1 hour for my students to get comfortable with it.
3. If you are a beginner, any A1 textbook would be good.
4. Games in Russian can help. Metro series might be good if you like FPS
5. Subscribe to channels on YouTube. Find the topics you are interested in and subscribe to similar Russian language channels.
6. Try to write phrases in Russian. Maybe comment something on the internet or write a plan for a day in Russian. Just google the separate words you want to know.
7. Find some Russian meme sources, subscribe to VK, or join some Telegram channels. Russian side of the internet is huge and has a lot to offer.
8. Russian is a very challenging language, so in order to speak it properly you need to be really determined, but I've seen people who progressed relatively fast. Just learn new things all the time and be motivated. Good luck!Sailing, snorkelling and Snuba combine to make this a catamaran cruise with a difference. In the morning, snorkel in coral reefs teeming with tropical fish and then Snuba in the waters off Bavaro. Tuck into a tasty lunch in a beach restaurant before hopping back on the boat for more fun. Enjoy a party on board as we sail to a natural pool for a swim.
Catalina Island is considered one of the best diving spots in
