What family?

I really don't have a family. I have a biological mother, who is a bitch. I am always paranoid about her because she usually has something u her sleeve. She is VERY manipulative, and she is VERY sneaky. And I have a biological brother, who is so condescending towards me. sometimes he can be nice, but most of the time he is an asshole. IDK why either. I never did anything to him. And I have a biological sister, who is mentally ill, and pretty much tore my family apart and didn't care and left me in the dust to deal with the aftermath she created. and I have a biological dad. He is a VERY awesome person, but he has his problems... I love him too much to say what those are. but you see? I really don't have anybody. I don't have many friends, and the ones I do have I don't want to bother all the time complaining about my life. I just don't know what to do anymore. I have no one.
