I am sorry for everything U have been thru as well as Ur friend. As the others have said, "he is lucky to have U there & be so supportive. How l long was Ur friend over there & is he out of the service now (if U don't mind me asking)? I don't know if Ur friend received initial help from the VA when he got back...Such as: Therapist that specializes in PTSD, Support Groups that they offer, & or Medication? I am not a doctor, but I would first recommend that he seek all the services provided from the VA.
I too, suffer from ptsd (but mine is not related to serving in the Military). However, my husband (23-years of marriage, 7-kids, 3-grandkids) served in the Military. He was in the Iraq War...The first invasion in 2003 & was there when it started. He was shot, lost his teeth, injured other parts of his body, & then suffered a heart attack before they could life flight him out. He went there as one man & came back another. He left 210-pounds & came back 135-pounds + no teeth :(
His PTSD was noticed by myself & our 7-kids right away. One of my daughters & I took an 8-week support group classes. This was for immediate family members & spouse or girlfriend (as we only had females in this particular group). I read anything that had any information on PTSD.
I'm sure everyone deals with it in their own way. Keeping it locked up inside of themselves & doesn't want to share the deep personal issues that comes with combat. Or being completely comfortable to open up & freely talk to someone. I think having a Mental Health provider from the VA & regular scheduled appt's can be good for certain people. In my husbands case, he did try the group support setting. He didn't even stay for the whole mtg...Listening to the others talk just was too much of a trigger for him that he will not attend them again.
I'm so sorry I rambled on. I wish U & Ur friend the best in Ur recovery process.
Ur Healingwell Friend,
