Hi jamestor
Welcome to the forum.
Public support groups seem to be hard to find, which ever part of the world you live.
As for employment, that should not really be an issue, if you can work and are able to do the job applied for without a problem. Then just go for it, you should have the same chance as anyone else. It would only be a problem if your PTSD issues interfered with your work.
Take care and keep reading and posting.
