When will it end

I am a 16 year old boy and have been suffering depression for the past 4 years and still on going. I’ve had problems with my brother and parents, my friends and my faith, and lastly myself. I don’t know what’s happening to me. I have complied with my parents and doctors rules and still nothing. I’m totally lost right now. I have attempted suicide many times but have failed in the process and I have been confined in the psychiatric unit twice already, but nothing still seems to have changed expect for the fact that my condition keeps getting worse and worse. I hate my life. I wish I was never born. I wish that at least one of my attempts worked so that people could live the way they wanted to live before I even came into the picture. Nobody in this god damn world loves me. They all have been lies. I don’t know what to believe anymore. I have done almost everything to keep my mind of suicide and cutting. I’ve tried frisbee, music, drawing, etc. but noting seems to work. I have made roughly a total of 500 slashes to my arms, body, and legs and I am going to add more. I feel so hopeless right now. People say that this will end, but the truth is this will only end once I end it. I guess suicide is my path. I’ve been deprived of so many things like going to school fairs, going to prom, hanging out with friend, etc. Right now I have no one to talk too because they are too focused on other things. All I can think of is my death. I have nothing else to live for. I’m don’t belong, I’m a burden, a hassle, an asshole, a dick, and a waste of time. I don’t expect anyone to reply to this because I know you guys are busy and all of that, I just wanted to let you know how I feel.
