Let’s not lose hope, I am sure we can find a way out. You will have to push yourself to start doing something. Take a responsibility and start working on it. This will promote you healthy sense of self. What is it that you want to do?

Hey friend, First of all, please calm down. Don't hamper yourself this much. I can definitely understand you as i've been going through this since a few months & sometimes even now, it has never stopped.. But one thing I can tell you for sure is that Stop Expecting so much from yourself, whether it is study related or anything else..as the more you expect, more responsibilities build up for you..you think more & more & the saga continues.. Instead try to find happiness in what you are doing, try to find intrest, make it fascinating for you instead of making it burdensome for you..remember to enjoy it, forget about the grades for once, take it as a learning process.. Because if we keep overthinking too much, then we aren't able to do even what we were able to do before.. And yes stay happy internally no matter what. Everything will be good. Don't worry. Sorry if this became too long.
