PTSD can manifest itself so many ways, and none of them are happy. I deal with it daily. Take care of everything else and the PTSD will follow. I am also diabetic and I also have sleep apnoea. My blood sugars are now quite well controlled and I have been sleeping with a CPAP machine since 1997. I see a shrink twice a month for the PTSD. It's a process. Stay with it and it will all be great all the way until the ride ends!!
