My wife is a mental health therapist. She does not specialize in PTSD or combat related issues. But she is well connected and I am sure she can refer a therapist that can help. I know this isn't what you've asked for, but it is what I can offer.
Thanks for your service. Having never served, I cannot imagine what you are going through but I encourage you to reach out and get some help through any avenue possible. https://www.vetfriends.com/army.cfm This might give you someone to chat with.
