<human>: Can you give me the gist of the text in a nutshell?

Hello reddit I'm 15 and have had a really horrible relationship with my father since i can remember. He used to make fun of me and my sister constantly causing both of our self-esteems to plummet, and for us both we turned to food and went from healthy to obese. For all of middle school i lived with my mom while avoiding my dad all i could ( seeing him around once a month), i was very was obese and in the last quarter of my 8th grade year my best friend got hit by a train at the train tracks by my school and died. After that i lost around 60 pounds and decided to move in with my dad to go to the school by him (my mom lives in what you could call the ghetto while my dad lives in a very rich neighborhood), i loved the school but my home life was horrific. I don't want to go into details but i got so paranoid i would have panic attacks almost every night and maybe get 2 hours of sleep. On Halloween i decided i wanted to leave that house, go to my moms and never come back, i didn't talk to him for around two months while at my moms, going to my new school. I started talking to him again and he has seemed like he really wants to repair our relationship, but its so hard to not think about the horrible things hes put my mom, sister, and I through. So I'm just wondering if there is any activities that we can do to help repair our relationship, that are not therapy ( I tried that in middle school and he never came to any of my appointments). Please reddit I just want to have a dad, thats really all I've wanted in my life.
