Valascus,
Listen and heed what Tom Bass is saying. I don't want to diminish what you are going through because I know it has been rough. But you are only 24. You have lots of time to turn this around. Dude, when I got out of high school I had an academic scholarship to go to college. I got involved in drugs, drinking, and playing in a band. Through a combination of my own bad choices and some bad luck I found myself in a similar situation at about your age. While my grades had been good at college I quit because I wanted to concentrate on my music. When you quit, you lose your scholarship. You can't get it back when you return. Around this time I ended up in the wrong place at the wrong time and was assaulted by 8 guys. My hospital bill was astronomical (at least to me, it was at the time.) Soon, thereafter, I was married and had a child and we were barely getting by. Anyway, to make a long story short, I applied for financial aid, worked, and went to college, graduated, and was able to get a job eventually in which I could pull myself out of the hole. Now at 45, almost 46, my wife and I have quite a bit saved up for retirement and if the economy doesn't collapse we both plan to retire in our 50s. At 24, I never would have believed it. It's hard to see the light at the end of the tunnel when you are young, because it's a long tunnel.
If you believe you can get out of this you will because a strong belief will cause you to take actions that will eventually turn this thing around. Make a plan, and stick to it. You will have setbacks, but, one day, eventually, you'll look back and you won't believe how far you've come.
