there’s two sides to every story. how much of this poisonous relationship is them, and how much is you?
realistically evaluate how much of this toxic relationship is your doing, and do your best to make peace NOW. this will be better for everyone in the long run.
even if you are not indebted to your parents for the rest of your life, you will still have a crappy relationship with them and that’s even worse.
try to fix the relationship first before throwing in the towel
