Troy,
Your primary care physician is most likely aware of your PTSD any way...admitting to it and asking for help is not going to be a surprise to him/her.
Many Vets of our time are seeking the help we need, and receiving that help...help that was not available to us when we returned home.
You've toughed it out long enough, Troy. It's time for you to take whatever steps necessary to help yourself. You can spend the rest of your life battling your demons, or you can spend the rest of your life having a measure of peace...
A perfect peace? No.
Peace so when you go to bed you can rest, most of the time be out of high alert, not need or want anything to numb your feelings...yes. Enjoying weeks or months of being free of the anguish, freely give and receive love because you know you can and you want to do it? That you are worth it...?
Yes

Your hesitation is understandable, Troy. Perhaps part of it is actually admitting to the PTSD and being tired of going it alone...
and there is nothing wrong with it; if anything, it can be the beginning of the better things you want and need in your life.

In Peace
C
