This isn’t your doing, so please don’t feel guilty! Your mother sounds like my dad; I still live with my parents and I choose to have very little contact with him because of the kind of behaviour you describe - he likes causing a reaction because he is an empty bucket with a hole in, emotionally speaking. If your mother is the same then she will do nothing but take until she’s drained you, you literally couldn’t fill her emotional void. You are doing the best thing for yourself in a game you can’t win. It’s not your job to fix your parents.
