Depression From Family

Hi am 19 year old and I been dealing with a situation about my dad. I recently spilt from him four months ago but am still dealing with the emotional stress he left on me. Am pretty sure my dad has mental issues and that's the reason why I left him because how crazy he acted towards me and treated me. He would get these switch ups and start to yell at me for no reason it got so bad to the point he was screaming at me at a gas station because I didn't know how to park the car right to get gas and the gas clerk had to come out to check to see if everything was okay and then I got so tired of his behavior towards me I decided to leave and I told him but he then called the cops on me and started making me seem like I was the issue and started telling his family on the phone that I went "crazy" and ever since that day I just left with my mom and I recently found out from a family member he told them how he doesn't want anything to do with me anymore and disowned me. I really don't know what to think of this. It's crazy really. When I was a kid I knew he was so filled with hate and would get these anger outburst but I thought he learned from those mistakes but now..after all that I don't know what to think.
