I am muslim too and ive had a moment in my life where i wanted to end it but didn't because it was haram. You know, in the end its all gonna lead back to allah. You know allah would never burden you with something you can't handle and its all just a test. keep your head up high. The best thing to do in this situation is to abandon your "friends" and focus on yourself and what you want to work for. Set goals you want to fufill in both dunya and akhira. Try not to think of the negative things going on. Surround yourself with things that make you happy. Halal things that keep your mind off of the bad things. I hope things gte easier for you.
