Repeating past mistakes

Basically I am 25 on my second marraige and 4 kids. I had history in my past liek most people and the only way to deal with it was repressed anger which accumilated each time i got angry. after a while i could black-out when i was angry to find I had done wierd and nasty things which I wouldnt normally do. Due to this I lost my first wife which then made my anger even worse. I attended an anger management course run by the local authority which turned out to be a farce but i went every week untill it ended. I saw a psycologist (wrong spelling) who diagonosed post tramatic stree, i ended up doing short spell in prison. Whilst inside went on a course called 'enhanced thinkign scheme' which did wonders.
Came out and ended up with a fantastic women, my ex decided it was time to much about with access to my children and that added to my problems, but everything was ok with my new wife and kids, then for soem reason i started to become anger, but in a way completely different to before. Now when i get angry i feel empty and that im only anger for show, but it still doesnt stop.
Due to my court case with ex over access i ended up having a full on shrink report being carried out where he said i was o.k but had ADHD (attention deficit hyper-activiy disorder). Im have been on a list for helkp for 3 years now and still nothing comes. Due to shrink report being issued in court procedings i am not allowed to show it to my doctor unless ex agrees but she doesnt, so I cant take it to doctor to get help for ADHD.
I cannot talk to anybody, now my current wifes wants me to leave, I feel like my heart has been ripped out, 4 kids no home, 2 ex-wifes and an anger problems which seems to mutate when i pin done whats wrong and how i can change it.

I live in Brighton, East Sussex.
I need help, I need it soon or I am going to end up in a place I dont want to be phsyically and mentally
