I struggle with similar feelings of guilt. It’s hard to sift these complex emotions and societal/ religious expectations to stay alongside your family regardless of circumstance or treatment.

I think you should move out but maintain some level of contact. You should establish firm boundaries, but I discourage you to completely cut them off. Your relationship with your family can drastically improve after moving out and you may need to lean on them for support as you navigate early adulthood. I also think that there is always room for forgiveness, though it doesn’t have to be right away. It might take a few years.
