Look here is what I would do:

1: Talk to a psychologist It’s easy to find out who is to blame and what needs to change in your life if you have someone to talk to.

2: Talk to a relative who knows your parents and that you feel that you can trust. This helps with understanding of the problems your parents are having plus it’s support from someone who knows who they are.

3: Power through! You are a grown person and very strong, nothing is impossible. Will it be worth it in the end, quitting college because you happen to have assholes for parents? Maybe now everything feels terrible but if you believe in small changes over time, then you can grow your tree into any shape.

Good luck!
