Currently off work diagnosed with PTSD (Post traumatic stress disorder) unfortunately in my line of work I have witnessed the worst of human behaviour and what they are capable of doing, see my share of death and carnage. You think your relatively unaffected even after 20yrs until your asked to go back to something you know you can longer do. My choice was to continue on and block it out or admitt I had hit the wall and seek help which is where I am now working with my GP, Psychologist etc. Fortunately I have family and some ex-workmates who have been down the same path. My outlook is to try and remain positive and keep busy go to gym etc and hopefully in about 6 weeks will have a new shed up and can focus on a sandman rebuilt which would be great. Its one of the hardest things I have ever had to do admitting I could no longer do my job and in the end my doctor made the decision for me. I think that is the break through moment for all men as we find it so hard to admit what we probably see as a weakness in that we need help or assistance to cope, all I can say is dont be talk to your partner or your gp before your in a hole too big to get out of, cheers.
