How can I be a good family member?

I am definitely the black sheep of my family. I am such a goddamn failure and I want to not be related to anyone. My family is so amazing but with me they are a white tablecloth with a gross stain on it. I'm the gross stain. I like my family but not with me in it. I am not necessary. I am like an ugly accessory. I am useless. I cant ever do anything right. Everyone lies to me and tells me how great I am but I know they hate me. I wish they would tell me the truth. I cant stand myself and I think that God was drunk or something when he made me. I wish I wasn't born. I prefer my dreams over reality. I wish my parents had used condoms and stuff instead of trying to conceive me. I wasn't worth the pain. My siblings are definitely better. They are such great people compared to me. I am a disappointment and a piece of ****. I don't even understand why anyone would ever want to be my friend. I would certainly not want to be my friend.
