Nowt I can say but don't let the bastards grind you down. In some ways the mental injuries soldiers get might be worse than the physical ones Big tough soldiers aren't supposed to cry and no one like to think of it happening – so it all tends to get swept under the carpet. Its easy to deal with someone who got their legs blown off, its much harder for the powers that be to deal with a soldier with mental injuries.
I have looked after WW2 veterans with PTSD – it didn't come out until late in their lives but it had coloured their whole lives. I will never forget 50th anniversary of VE day when I was looking after them. the tears and the distress really took me aback. for many of them it might have been the first time letting it all go.
So good luck. Seek support and fight for what is right for you.
