What do I do to get on the right path to get PTSD evaluation?

Sounds like you are pretty early in the process. I would recommend getting an advocate to help you. Whether that is a Service Officer through a non-profit, someone from your State Commission or a third party through another org you need to get someone to help you get evaluated. Basically it will be submitting claims to service connected issues. good luck

A lot of states have veteran's service centers where you can find resources such as counseling and group therapy that help. If nothing else, in group therapy you get to really see that having PTSD doesn't mean you are alone and that living with it is possible. It helped me. I felt alone and somehow flawed before I got help. It meant the difference in being able to reach retirement and live a somewhat normal life.

You have to file a claim with the va this can be done in two ways with a va rep, or an attorney who does va claims I had an attorney once your claim is filed you will be notified by mail you will have to interview with a va specialist note this is all they do interview people for PTSD you will be rated on the answers you give to the questions you are asked you might want a attorney who does va claims, keep going to the va for help do not stop join a group talk about it with other veterans it will never go away but talking about it helps the mind rest. Good luck my brother
