Why does it seem that no matter what I do I can't seem to please them?

My parents raised me up in a baptist religion and that's what I have believed my whole entire life. I am turning 17 soon and I feel like my life has done an 180. My parents built their dream home, but it's not the home that makes the family, it's the family that makes the home. Both my parents are manipulators and are being very cruel, mean, and ridiculous. Example: My OWN dad calls me fat and I won't amount to anything. Threatens to kick me out. I can't hang with my friends because of him and I know when I was younger he never gave a **** on what I do. He's never cared but now he likes to manipulate me and put me in a lousy position and it sucks. My mother is depressed and doesn't care. I just want to know is it me? Or them? Or God? I've tried to hold on with all grasp of Christ, but this has been going on for years and in the bible it says you will be rewarded for your good deeds. Now I know it isn't a huge reward but just give me a pat on the back so I know he's there. I really don't know what to do, think, or believe. I literally have no one to lean on and I am suffocating here. I am someone who ALWAYS puts others above themselves to make them feel better no matter how much **** I am going through myself. I try so hard for nothing, I don't know what to do! Help?
