Yes, physical pain is common when you are hurting emotionally. I am so sorry you are going through this. Detaching is a good idea right now. Sounds like you are not getting any support from your family - you will have to look elsewhere for support. And seriously think about how to get yourself out of the situation in order to protect your sobriety. I had to mostly detach from my father after a couple of years of sobriety. It was awful. But no one in my life made me want to drink the way he did. It was a complicated family dynamic, but there was no fixing it, as far as I could tell. He passed away last year. At first I felt guilty that we had not had a good relationship leading up to his death, but I have mostly forgiven myself. I'm here, sober, and living a good life. I felt he was trying to tear me down, and I wasn't going to have that. You need to take care of yourself, first and foremost.
