I left home at 17 and spent a little time homeless before getting life sorted. I didn't go no contact and looking back that was a mistake. Nothing I ever needed came from them and they were only a drain on my resources. I am now 38, so 21 years out, and I am now fully no contact for 9 years and they have been the best 9 years so far. Not saying you have to go no contact, but if you do you will survive.
