Hi Phil,
Welcome to MyPTSD forum! :)
If you suspect that you are suffering from PTSD, that makes it all the more critical to get an official diagnosis. The first step in recovery and management is knowing what is wrong, so the appropriate steps can be taken to make it better. PTSD is not a disorder that should be self-diagnosed and the sooner you are able to meet with a mental health professional, the sooner you will be on your way to healing.
Wishing you the best.
Debbie
