Learn how to fight. If you can talk things out with a therapist, do it. Don't take pills. Work out at a gym. Run, every day or nearly every day. Find something you like and want to do in the future and dedicate your 100% to it but also don't forget a social life. Not everyone's an asshole. Notice the toxic people in your life and subtract them from your life. I don't know if this helps at all, but that's how I operate. The best revenge is success. Fuck them, do things for yourself.
