My trigger panic attacks. ( I am not sure how to put it, or separate it, or describe it.) Maybe it should be described as day-terrors. I think I have described it similarly on other posts under different questions. ...but I just got through one. As I have slightly described before; its like a damn breaking panic attack that just rushes in. My reaction is going into a scream like waking up out of a nightmare. Accept I am i it awake. I can control it coming on. ...but when no one is around or home. I let it out. My face hurts, it gets hot-warm in my nerves all over, my muscles ache. I start screaming as I am being terrorized by some horrid creature inside me. Like a horror movie, except I'm running inside me from it. Not all of my triggers or panic attacks though, come about to a point of a day-terrors, as I have just described.
