I'm going to go and get vaccinated against the wishes of my (anti-vaxx) parents.
What has your decision to get vaccinated against your parents' wishes done to your relationship?
I've cut my parents out of my life.
Your parents have your best interests at heart, even if they are wrong about vaccinations. Breaking off your relationship because of differences of opinion is not right. Talk out your concerns with them but don't shut them out.
It wasn't a difference of opinion. They are emotionally abusive and I'm protecting myself.
Going no contact isn't a decision to be made lightly. While I agree your parents are not making the right decision, perhaps not talking to them ever is going too far.
