Yeah, I understand. I was 17 once. Trust me man, things will get better. There's no reason to continue to try killing yourself. Also, there will be a lot more that will miss you than you think. It may not seem that way now, but I assure you its true.
Basically had another two failed suicide attempts in the past two days, missed work because I had taken an overdose and my Mom drove me to the hospital. Was sick as a dog for a few hours, and had another load of 'you're a failure, do something with your life' from my parents yesterday. Oh, and if I don't go to work today, I'll mostly likely lose my job and get kicked out my house again.
