So some base context, I've never had a good relationship with my parents but my younger brother (we have a 4 years age gap) have always been treated much better than I was, I always thought they were just treating him that way because he was younger but recently about 3 weeks ago my parents had an argument and I overheard them talking about me and I'm not supposed to know but now I do, that i'm apparently an accident and i'm supposed to be dead, but ever since that day i haven't been the same and everyday it's getting worse and worse, I cry more everyday that goes by and I don't know what to do, I have a girlfriend but I want her to lose feelings for me because I plan on committing suicide, but I’m still not sure what to do.
