"You can't leave me alone."

I moved in with my dad when I was 15, but I still felt like my mom and little brother were my responsibility, and that I let them down by leaving to live with my dad.

I told my dad that I wanted to go back to my mom's, and he said things like, "You're being selfish," "You can't leave me alone," "I know you have a better heart than that; you're not like your mom," or "You're two-faced as f**k." 

He would get mad at me if I ever told my mom about my worries or anger towards him, and he would then say nasty comments until I was a crying mess. Then he would send me to school while he would stay home and complain about me to our downstairs neighbors. 

I still can't get over feeling like I've betrayed both of my parents. I still feel responsible for my parents and little brother. I can't help feeling like I'm trapped in a corner.
