How do I stop being a control freak?

I'm still a teenager, but I want to become a good person before I move out and start my own life. I had a pretty abusive dad, who abandoned me and my family when I was ten. Ever since, I've been the biggest-ass control problem ever. Tbh I hate anything I didn't decide, anything that didn't go my way, anything that isn't EXACTLY how I want it. This isn't the way to live. I really want to improve myself, and I think this is the first step, getting over my controlling behavior.

Has anyone else here delt with this? What is your advice? Anything is appreciated.

Thank you so much!
