BlaDeBla that sounds really awful. I've been assured it's a woman only closed group, so hopefully wouldn't run into that sort of problem - I definitely couldn't talk about it in a mixed group I don't think.
I have done a couple of groups before, one for pnd and one for anxiety, which were helpful to an extent, but I guess addressed symptoms rather than the actual cause. I think I am ok with the group therapy concept on the whole.
I was put on ADs (citalopram) for the pnd and anxiety, and found them a great help to get out of that hole to a place where I could start helping myself, iyswim, but they weren't magic for me, found a lot of anger coming out while I was on them. Maybe again that's symptomatic, I don't know. At the moment I'm taking the contraceptive pill to keep me level emotionally - sounds a bit but is working for me so what the hell.
I can't talk to DP because his sister had some similar and very severe issues when they were younger, and I think it stirs up a lot of stuff he'd rather not think about. I'm ok with that, the last thing I want is to get better at his expense. He was the very first person I told about it, and gave me, I dunno, the strength almost to actually be able to talk to the doctor about it, so that's something I'm very grateful for.
The nightmares are a really weird thing. They don't happen often, and they are not explicit or flashbacks or anything like that, just containing the abuser (my mum's ex-husband - though I've never told her what happened) and have a threatening air to them. The sort of dream that sticks with you for a couple of days, making you feel faintly uneasy. The oddest thing was that I was doing fine for ages, then I had this odd dream one morning which really shook me up, and lo when my mother arrived to pick up my son for the night, she said actually she'd gone to see him that morning around the time I had the dream - make of that what you will. It really shook me up.
I see what you are saying about acceptance - as I mentioned my SIL has had some similar problems and when she talks about them you can tell she is very comfortable, if that makes sense, not embarassed or ashamed, just very matter-of-fact. Whereas I cannot keep eye contact with someone if I talk about it, I feel sick and nervous and scared.
I'm really grateful to everyone who's replied to me, especially you Run4It. I think really I knew I had to do this, for my own sake, and you have made me feel a lot less worried about it just being a negative thing. Thank you.
