I am a retired service member and have been for several years. I have been to the E R due to severe panic attacks in the last couple years. I was never shot in combat and have always considered ptsd a sign ow weakness to an extent. I witnessed some terrible incidents and one in particular left me with an immediate reaction of violent vomiting due a certain odor and taste. The texture of the air was like steam. Now for example if I were to drain water from a hot water heater and the steam hits me in the face I vomit and that is an easy way to describe the action
