=( do all you can do - take it one step at a time. Is your t working with you on containment? or does t just finish the session with high charged stuff and let you leave? i am learning that with dissociation, ending session in a containment mode really really helps. so therapy becomes the place to open the jar - then put the lid back on and go back to where i was. i'm sure it won't always be that easy, but t is doing containment after every session so that it is a pattern that i fall in to. it also makes therapy less scary becase i don't fear the overlap of emotions into my life as much.
as for family - only you can decide. i did finally stop talking to my family. it took me 10 years from where you're at to make that choice final (and really they helped the decision with a fight and ultimatium). And things are deffinately better for me now that that happened. I can't say if that would have been true for me at 21. but 31, i barely remember that i have a dad, yet alone fearing the controlling entity that he was in my every waking moment. if i didn't currently like with my mom, i wouldn't be talking to her either. but the ties are so thick with her - almost strangling - i don't know if they can be cut.
try not to look too far ahead right now - just do what you need to. now is not the time for far planning... work on centering and taking care of you.
