Troy, never underestimate the love of family. They may not understand at first, but hey, neither do you (about PTSD). I think both you and your family deserve to have the "real" you. Sooner or later the "fake" you will slip off like a mask. I think they will be behind you as long as you keep them in the loop about PTSD.

For better or for worse...

You were there for your country, now let your family be there for you.
