Giving Up

I feel like giving up right now. Nothing is working for me. I'm sad and lonely with nothing to do. I can't take this anymore feeling like this. I feel like I'm nobody. I can't focus on my schoolwork, don't have a job, and don't know what I want to do in life. I have over $4000 worth of debts which I can't afford to pay. Everything is going downhill for me.
