I can definitely relate to your family issues. One thing that helped me was to just not react to them. Instead I just acted like a healthy person would even though the family dynamics weren't healthy.

I think a lot of times that kind of behavior is masked pain and if you do little things to show them there's no need for all the drama to get attention it helps. After you get used to it it's actually kind of fun to watch people have to figure out what to do when you are refusing to play their games. Politely refusing, so they can't actually point to anything you are doing "wrong" but still refusing.

Once the energy is freed up from pointless family drama you'll have more for the rest of your life.
