Be careful when burning your bridges, because you may find down the road that you need someone, and that "someone' just MIGHT be family. For instance, if you're in the hospital, and you're unable to make any decisions for yourself, who would you want to make decisions FOR you? A stranger? I doubt it. I would think you'd want family members to make the decisions regarding your health for you. So be careful about totally rejecting family members. You may live to regret it.
I understand that some family may be toxic to us. We just don't have to spend alot of time with them. But don't cut them off completely for the above reason. It could be VERY important to you if/when you're in the hospital.
Think this thru very carefully before you cut any ties. I wish you the very best. God bless and please take care. Hugs, Lee
