Before a year ago I was unaware that I was really having panic attacks when I thought that I was having food poisoning. I never had any limited attacks then, just full on panic that lasted maybe 10 minutes to half an hour and only happening perhaps twice a year. A long with the flushing, prickling, palpitations, numbness, etc, I would always get queasy and then vomit. After vomiting the symptoms would begin to dissipate, convincing me that I was just having a bad reaction to whatever I ate.

Recently I have experienced much more limited attacks much more frequently, which involve me getting nauseous a lot of the time, but not always throwing up (I resist doing so). The few times a year where I outright PANIC (I'm going to die panic) I expect vomit.

So yeah, anxiety makes me feel physically ill.
