just don't care, even if you don't believe it at first, convince yourself it's not worth it. It may seem too simple and not schizophrenic enough like the other anons in this thread but that's it. Just say 'ok whatever' to yourself and move on. Also start thinking logically about things. Think of the pros and cons of every decision you make and a couple of plan Bs. This might seem counter intuitive since you're trying to stop overthinking things which causes anxiety, but if you're not a genuine retard, thinking about this stuff takes a couple of seconds at most and (this is the most important part), once you thought about something logically, you don't have to do it again. You already know the results and since pretty much most of our lives are routine at this point, you won't have to do this a lot after a while. Once you 'mastered' thinking like that, you won't have to overthink shit since you already have it planned out.

I'm not OP but I fucking can't. Its innate, unavoidable. If I have to talk to a new person or do something im not used to I feel the sweat glands open up and my heart start pumping. No matter what I try to tell myself my body will freak the fuck out in the simplest of interactions. Its really impacting my life. I like to be alone, nice and safe from the world 
I fear failure and rejection so much that I'm afraid to do anything. It makes me feel worthless and like a cesspool of wasted potential.
