I just wanted to see if anybody else ever feels like this.... its happened 3 times now. 

I never had panic attacks in my life before about 3 years ago when I had my first one. I didn't even know what was happening. Trembling legs and arms. Hyperventilating. Hives. Impending doom. ... had no clue what was happening until my coworker gave me an hydroxyzine he had for allergies. Worked like a charm. Didn't have another panic attack until 6 months later. Had a really bad attack at around 3am after waking up in the middle of the night. This time I went to the hospital thinking I was dying. They didn't run blood tests but gave me a lorazapam or whatever it's called and sent me home. The symptoms went away for a short time but for a week I was constantly anxious. Couldn't work or even leave my bed.... fast forward to this week. Panic attack Sunday night and now I have had non stop anxiety since Sunday. Won't go away. 

Does anybody else have a panic attack hang over for almost a week? This is getting really old.
