At first I would get to feeling like I was shutting down, dissociating, zoning out... then I couldn't move my body. Then my shoulder or arm would start shaking some and my abdominal and neck muscles would tense up. Sometimes I fell to the floor, and don't remember it happening. The times I DO remember it happening, I couldn't breathe very well and would go like a minute without breathing at all, and when I did it was squeaky and shallow. Then I would go limp and just lie there for a long time... 5-10 minutes. It was really draining. I really thought it was some sort of different panic attack at first. But when I told all that to my GP he called them pseudo seizures. I had all sorts of tests done, EKG, EEG, MRI, tilt test... all came back negative.
