I’m so sorry, Cdogger! I get on really well with my older brother now, but he would wind me up when we were children and rarely was the one to be told off (I was also “too sensitive”) so I can relate a little. I hated him for a few years but not now.
I concur with the others; blood ties don’t mean you need to forgive them. Family, ideally, should have your back, not be trying to score points off of you or make you feel bad about yourself.
Think about what you’d like to do for yourself here? If they don’t have your best interests at heart, you need to look after yourself first.
