I don't know how to deal with my parent's divorce without ruining my own life :/?

First of all im so sorry you had to go through so much crap because of their mistakes. If you know you did nothing wrong then dont let anyone change your mind.I think you should talk to your mom about everything that happened this past year. Get a job so you can get your own apartment. You can take care of yourself instead of depending on anyone else. So get your own apartment then save money for college.Good luck!
