You're a step ahead of where I'm at. I fucked up my college(and part of HS) because of anxiety and other shit. Took 7 years of being on again/off again to finish an A.S. in bullshit that won't get me anywhere, and have a transcript that will probably prevent me from ever trying to get a bachelors. The job I'm working has broken me, but it might be a good thing. I have a very hard time caring what other people think now, and I'm slowly strangling the voice in my head because it tells me things that I would beat another person for saying. I'm working on getting some certifications now, and being more successful at it because my problems were never intellectual, they were always with confidence, anxiety, and that voice telling me that I can't do it or it won't be good enough. It's no longer a matter of worrying if I won't be good enough, or if things will be too hard. I finally understand that I won't be good enough every time, shit will eventually go south, and that people will tell me no, but I'll be fine anyway. I've made and will continue to make mistakes, and I have so many regrets that it makes me want to vomit, but I'll be fine if I try to do better, and so will you. You'll be fine because you deserve to be.

Talk to a professional about your problems. They can probably prescribe something(drugs or actions) to help. Watch some motivational videos(I have a few favorite if you want) and take a break, you're probably overworking yourself and getting stuck in a stressful feedback loop. Take a day for you, and do some things you enjoy. Take another day to evaluate who you want to be and whether or not the shit youre doing is getting you there, and change your plan accordingly. Don't worry about all of the other inane bullshit going on, it'll be fine until you get back.

Always remember that people say no, bad things happen, and we sometimes fail, but you'll be fine regardless.
