Not this soldier! ;-) I am the man in discussion here, Tardis (Dean) is dating my daughter. Don't have PTSD, quite certain of that fact.
However. Did suffer combat stress after being in the Golan Heights in the 70s. Suffered many anxiety symptoms and became a heavy drinker. Lasted perhaps half a year. Then - stopped drinking, received treatment, and am well since.
Huge difference between my brother and myself. Eric was not a talker. Kept everything to himself, including his emotions. Let it fester. Whereas - I am an open person. I talk, express emotions, even crying and so forth. Always have been so. Our family participated in a study on PTSD this past year. Physician conducting the study theorized my openness was a possible preventative measure. Akin to early intervention after trauma. That along with, perhaps my genetic factors are not as strong.
