Having A Tough Time In Life?

I'm having a tough time in life with my family. My stepdad talks trash about me and says I'm not smart. And my stepmom has lied to me sense I was 2. My dad just looked at me when I was born and left the room without saying anything about me, yet I still visit when he's gone all the time at work leaving my stepmom taking care of me while I'm over there.
