what is up with that feeling? My doctor put me on meds for that and said it was panic attacks. Meds didn't work and my "freak outs" got worse. I totally feel the irritation of not knowing what is going on. The way I explain the feeling is being almost asleep and some one jumps at you. the feeling is that brief second that you loose your breath and want to scream but can't. I feel like that all of the time. Some times to the point that i lock myself in a room crying and shaking.
I hope you can learn to control it and if you do tell me how you did it.
