Hi Turmoil
I haven't posted before, but will break the habit of lurking for this.
You're not the only one -- it happened to me as well (my Dad, too). Similar stuff to what you outlined in your post, and although everyone's experience is different, I do recognise the feelings you're describing now.
I think just starting to deal with it is the hardest part, as you have too many conflicting emotions coming up at the same time. I remember feeling completely paralysed by being pulled in several directions at a time, and angry and bewildered at not being able to get any kind of handle on describing or understanding my experience. If it's any help at the moment, it does get easier eventually -- it's not that you get to the point where it doesn't matter any more, but it will at some point stop taking over your life, although it doesn't happen overnight.
One thing that did help me was being told that you don't have to feel guilty about your emotions if you feel a certain way, then you do, and you can't change it at that point (although your feelings will alter over time). You're not cold, conniving or weird your feelings seem entirely reasonable to me.
Talking about it really really does help, although it is incredibly hard at first. There should be NHS psychotherapy in your area, although you need to exercise judgement some psychiatrists/psychologists are brilliant, others will be considerably madder than you. I speak from experience here... Also beware of people who try to offer you solutions you need someone who will listen and help you talk.
Possible ways of accessing help are: health visitor (I had a long talk with my children's HV when all was a bit much for me); if you can get a recommendation for a good GP you could visit them as an emergency/visitor and get a referral that way; major psychotherapy training schools will have clinics where they see people at reduced cost or free. And remember, it's not that you're mad -- you've had experiences that would challenge anybody's ability to cope, and a good professional will give you the space and support you need to begin to unravel your experiences and emotions and knit it into something new.
I hope this helps -- if I can be of any use, post a message and I'll keep checking the board. Hang in there. It does get better.
