Lifes pain

I cant cope with life anymore where ever i go problems occur, i want to curl up in a ball and die. life aint pretty i know that for sure but as i got older i didnt realise it would be this tough. no family to help me through my problems and no place of my own i can escape to. how i managed 18 years i do not know. what i have achieved in my life i have nothing to show. the anger that is around drives me mad i am going insane. i want to get out but i cant my life is trapped in a vicious circle. where did it begin. when will it end? i cant see a way out unless i end my life. there is too much misery and why is it only when i am around that things turn bad?
