this is a really sad story, idk what to say, have you tried therapy? if your still in school some of them have counselors or resources to help people out
if your not in school try going to a local community college to find resoures to help out, you dont even have to attend school often to get these resources
killing yourself is not the answer, as a devout catholic i can tell you that at least as far as i was raised i was told that suicide = eternal hell in the afterlife so please try to find some one or some way to work it out ok and good luck
