I am going through my 3rd bout of panic attacks (lasting 1+ weeks VS. one every once in a while). 1st time I was about 14, 2nd time 27, & now again @ 32. I take Lexapro & usually only take .25 mg Xanax on an 'as needed' basis but have been taking one every 6hrs for almost a week since this 3rd bout started. Some days are better than others & I am trying to cope the best I know how. I saw a new therapist that I like very much for the 2nd time yesturday. I was telling her about my history (mom & boyfriend fighting everyday!) and she mentioned that she thinks I may have a touch of PTSD.....Ugh, like I need another label :(. I have researched panic disorder to death but do not have an understanding of PTSD. Do both trigger the 'fight or flight' response? I tried to research it online but the facts aren't very clear. Can any offer advice??....it would be most appreciated :)
