Anxiety and Physical Illness

Last Wednesday, I was supposed to go to CPT group.  I ended up stuck in the house with serious anxiety issues that made me marginally functional at best.  Out of the blue, I felt anxious about everything and nothing all at the same time.  The feeling was so intense that my adrenalin kicked in so violently I felt sick.  I don't know why it happened, but I am starting to see a pattern in my behavior that worries me a lot.  Before Iraq, I was in great physical health.  Now, I have borderline high cholesterol, respiratory issues, severe allergies.  It is like my body is attacking itself.  The only common element I see that has been constant across all of these health issues has been my severe anxiety and the burst of adrenalin that goes with it.  It can't be coincidental.  I firmly believe that prolonged periods of anxiety and adrenalin induced hyper-vigilance is deleterious to your health.  I am curious is any other veterans or caregivers of veterans have thought about this connection.  I hope to hear from you all on this subject.  I find it hard to believe that I am the only one who suffers these symptoms.
