I've had what is presumable panic disorder for the past two years now, and today seems to be particularly bad.
Earlier, I started to feel tingly all over, and when I noticed it, I went into a short panic attack (chest discomfort, extreme fear, urge to leave the place, etc). Now the tingling sensation won't go away, and I feel somewhat dizzy. My heartrate is fine, there are no mental changes in the slightest, and my legs feel slightly weak still, like I was just scared quite badly.
