I had a very similar childhood to you Foley, and a very angry destructive younger adult life where I was happy to take out any anger and frustration I felt on anyone at all who happened to be in my path. At night I was a sobbing, unintelligible wreck and predictably became addicted to alcohol and drugs to blur it all away. Compared to the way I hadnled things you already deserve a medal. You are doing all of the right things, you're seeking professional help, taking notice of that professional help and understanding that there is nothing wrong in needing assistance to deal with the way other people's actions have made you feel.
I know you have tried various things that haven't worked for you but in conjunction with the medications you're now taking they may well, so don't rule out anything just because they have't worked once, so keep trying NLP, CBT etc and the one thing which really helped me and is free is exercise. I'm 52 now and I run about 12 miles per day plus other stuff soemtimes and the difference in my moods and abilities to cope if I don't do a reasonable amount of exercise is really marked. Please keep in touch and let us know how you are doing and we are always here to tlak to if you just need a sounding board- there are more people with abusive backgrounds than you might think on here, and we're an ever ready ear should you need us.
