Right, back again with a little more time.
First of, the anger isn't necessarily directed at you. My personal experience was that I would sleep badly every night due to nightmares, intrusive thoughts etc... This affected my ability to cope with things throughout the day.
PTSD sufferers are constantly in a state of hyper-arousal. That just means that there is an excess of adrenaline in the body and that because of the way the trauma is processed in the brain the brain prepares the body to relive the original trauma(s).
As the day progresses, little things would gradually add to the level of stress / adrenaline / fight reaction and I would spend all day holding it in. Then suddenly when I got home to a safe place I would often find myself pushed over the edge by the slightest thing. Sometimes the kids would come running to me loudly, sometimes the fanfare at the start of the news would be enough but the result would be the same. I would be unable to hold back and explode. I did untold damage to my relationship with my ex-wife ( note ex ), and I fervently hope that I didn't do anything lasting to my kids...
My PTSD was diagnosed almost 15 years after the event. I just thought I was an "angry" person... So did all my family and friends.
I tried EFT... Found it calming but not a cure. Tried prescription drugs... Fluoxetine sort of helped, as did some sleeping tablets, but none of them cured it. What finally did help me was that my shrink referred me a consultant psychologist who used EMDR. I had ab out 8 sessions with him and walked out cured. I really was that miraculous for me. Sadly, about 15 years too late to stop me screwing up things with my marriage, but even after we split, the best thing my wife ever told me was that the kids had said "we like seeing daddy. He's not angry any more".
I've since spent time talking to my eldest now she's old enough to understand. Mainly to make her aware that having mental health problems isn't weakness. Everyone has limits. Everyone has experiences. Sometimes those experiences leave us very scarred and no one should be ashamed to ask for help.
Strangely, the behaviours that I now realise were very wrong, actually made me very popular with my managers at work. I was constantly hyper, "hard charging" able to juggle lots of activity... Only later did I realise that the level I was operating at was not normal.
Most importantly, I would say that you should be very mindful of your personal safety and that of any children involved. Joysmum said that she adopted "flight"... I was more "fight" though never violent to my ex or the kids, but I was very shouty and angry. He will probably not be able to predict or control his outburst... His anger might be at the cause of the trauma but projected onto others. It's a very complicated situation and needs proper professional help. If there is any chance of affording the care privately, then do not wait for the NHS...
You can all get though this, but trying to do it without help will be REALLY tough. I wish you all the very best of luck. PM me if you think I might be able to answer any questions you have...
