Text: title speaks for itself really... 
i just wasted $1500 of my parents' money.
i feel terrible.

edit: i guess it wasn't that i took the wrong class, but the class i was taking wouldn't transfer credits over to my university. so really it was my negligence to do more research in the matter. gg
Solution: TIFU by taking the wrong class for 2 weeks and only realizing it today
Reason: This title is appropriate for the given text post because the focus of this post is about a humorous situation caused by "taking the wrong class".

Now, solve this instance: Text: i occasionally use marijuana.  
  
my experiences have always been pretty mellow and relaxing, when i use a pipe and take a couple hits. it feels cool, i laugh a lot, food tastes great and that's that. 
   
today i had a different experience.  
  
my good friend let us use his vaporizer, which for those of you who don't know is a device that heats the weed so it releases vapor. it's cleaner and more efficient. anyway the plan was to vaporize and then see a movie. he shows me how to use it, and i vaporize quite a bit of weed, significantly more than the other two people i'm with. not that much more than what i would normally smoke, but keep in mind vaporizing is *much* more efficient with drawing out the active chemicals in the weed.  
  
initially, i felt the same familiar high coming on, just a little bit stronger. really pleasant and fun. then it becomes a little much, with my legs feeling tingly and my perception warping. as we we're about to leave to go inside the theater, it becomes **way** too much for me. i start to feel like i have absolutely no control over my own thoughts and vision. it felt like i was experiencing everything with a delay of a second or two, like living in slow motion. when i touched my face, my hand would feel really cold and really hot. i remember at one point rubbing the seat belt across my face because it felt *so* surreal. if i was at home in my room, it would have been an awesome experience, but away from home in a small car i started to panic really badly. i could have sworn i had a couple minor visual hallucinations. i told my friends **very** seriously "guys, i need to stay in here, i'm freaking out." at first they smiled, but as i persisted they got really concerned. fortunately, they were really understanding and stayed with me. i just sat there in disbelief with how intense it was. i wanted to be home.  
  
after about 30 minutes of what i can fully describe as *tripping balls*, i start to come down and feel much better. so we went and saw grown ups 2 and laughed our asses off. i apologized to them for pushing my limits and becoming a responsibility.   
  
moral of the story: don't go to a full-on [10] without knowing what an intense high is like first.
