Hey man you're in a tight spot right now. There's one thing you can do, and that's to bite your lip and put that foot forward. That's all you can do. Put one foot after another and hopefully soon in the future, those little steps will turn into a jog and hopefully into a full sprint, metaphorically speaking. Put this idea into everything wrong in your life. I was in a spot similar to you. I was 18 then, I was pretty popular in highschool and founded a break dancing circle that's going strong. One day depression hit and I lost everything. College, girlfriend, all my best friends and friends. I lost ALL of my friends and everyone that I knew walked out and gave up on me. My parents kicked me out and let me back in after a emotional talk. I still have no real friends now but I at least have control of my life. I'm depressed as hell sure, I have anxiety, so much so it's hard to drive but at least I'm inching my way, you know? First step is realize, there's suicide which you don't fully want and there's a future. Take that first step. Stabilize your school. Say "fuck it" and just go for it. I lost countless friends and now I realize, it's not a big deal. You will meet more in the future, you will meet people you will eventually love, but that is if you take those steps. Show effort in school so your parents don't kick you out, that's half the battle. The other half is biting that lip and inch forward. Friends? That can come later after all the rest. To be honest with you, it will be hard to maintain any friends while in the middle of a strong depression. Remember, you will meet people you will eventually love. Don't give up. Stay strong.
