A couple quick notes on this before I head into work myself. My wife is a licensed counselor, very gun friendly, Trump voter, Army vet, worked overseas for years and PTSD, especially for veterans, is one of her quite a few specialties. While her type isn't common, she isn't alone in the mental health provider community. It often takes some searching to find a good provider, remember you're the customer and finding a good fit is vital to getting better as quickly and as easily as possible. I'd connect you directly with her for help, but she's only licensed in WY, VA and NC, someone has to be physically located in one of those states for her to be their counselor.
For services without going through your employer or any other official channel, on your own dime,
MD Live is a good avenue for remote (online) counseling. It's owned and operated by Cigna, but a lot of high level professionals use it for confidential services where it fits for both busy lifestyles and not even a chance of someone seeing your car at a facility. My wife does work on there, you can do video or phone sessions, with good providers where you can search out who you want to see and choose your own fit. Counselors on there have to be licensed for at least five years, so you're not getting someone right out of school like most hotline numbers you'd call.
One thing though, magic words for any provider to sound the alarm as "mandatory reporters" are anything where you're thinking about hurting yourself or others. If this is ever the case for anyone out there, and you cannot help it, it's best for you to give yourself a time out and get real help before someone else does through Red Flag and whatnot measures.
Finally, I know very well myself how bad PTSD flashes can suck and big time "Bravo-Zulu" from me for reaching out brother, as well to others on this thread. Keep up the good fight, and feel free to PM me for more info if you want.
