Hey there,
I just read your post, and it sounRAB familiar to some things I've gone through (which you probably already know since I saw your post in my thread).
What I didn't mention in my thread, though, is that about 10 years ago, I had anxiety issues that were much more severe, but also more acute. By acute, I mean that I didn't notice them as much in daily life, but I would on rare occasion, have very nasty and very sudden flare ups. Basically they were full blown panick attacks.
My deal was this. I was in college at the time, and I was very worried about academics (very silly in retrospect now). It caused my OCD (a condition I've had since childhood) to manifest in some weird compulsions related to schoolwork, taking notes, etc. But I never had panick attacks, only compulsions like repeatedly checking and rechecking my notes from class.
But one day, I was watching a movie with my girlfriend, and I suddenly felt uneasy. Like an internal kind of unease where I wanted to jump out of my skin. Moments later I could no longer contain it: my heart started beating super fast and hard, I got short of breath, I felt like I was going to faint, everything around me looked pale, my chest felt like it was contracting, and I kept dry heaving (without actual vomiting). My girlfriend took me to the university ER, but moments before I entered it, the attack stopped and I felt perfectly normal, albeit tired. I had similar attacks 4 more times in college, and most of them happened while I was watching movies -- weird, I know. Afte college, my anxiety largely vanished, and I thought the panick attacks were gone...
Fast forward 10 years. I was driving home from work one day, and suddenly I get that same feeling of unease. No apparent reason for it. I'm in the middle of rush hour traffic, and it's all I can do to maneuver the car off the freeway and into an empty parking lot. I call for an arabulance, and when they arrive, I'm still in the grips of the attack. The paramedic gave me some water via IV, and about 10 minutes later, I was fine. They said it looked like I had a panick attack and was maybe a bit dehydrated. I haven't had a recurrence since.
I don't know if these full blown attacks are what you've experienced, but they sound pretty similar based on your description. Mine were harmless, hopefully yours are too. They certainly sound like it. Although I had school-related OCD in college, the fact that something recreational like movies would often trigger my acute panick attacks was something I've nevere really understood.
Oh yeah, I know where you're coming from with regard to the psychotropic meRAB too. When I was in college the doc gave me Paxil for my OCD. I took it for a few weeks but just couldn't deal with the emotional void it left me in. With my recent anxiety, my doc tried to give me Citalopram and Klonopin. I filled the prescription but haven't taken either one. Unless the situation is really truly unbearable, I never want to take another psychotropic med.
