I will not be checking replies but I wanted to offer advice that has helped me tremendously: OCD is rooted in internalized low self-esteem. Therefore, you need to externalize positivity to counteract the negativity and internalize that instead. So in other words, you need to commit to habits and activities that make you feel good about yourself. The biggest one that you can do right away is set a consistent regulatory schedule for your screen-time. Pick a time that you want to fall asleep. Then put all devices that emit blue-light away at least an hour beforehand. For me 90 minutes works. In that time, try reading a book for at least an hour and then meditating for somewhere between 10 and 30 minutes. Then go to sleep. Set an alarm and get up at the same time every day. Go to the gym and work out. If you don’t work out, start. Also take a walk every day and set aside time to work on school work without distractions. You will feel better in no time. I felt like shit just ten days ago but now I feel better than ever. Good luck.
