hey random noter here: I saw that you are 13! I just want to let you know from someone who came from an abusive household that things will get better. your stepdad being a jerk towards you is not reflective of who you are, it just makes him a horrible adult because he gets pleasure out of doing these things to you.
I spent many years of my life unraveling the mental abuse of my father. hugs. I hope you are ok.
