I have woken up in the middle of the night with an anxiety attack and it results in me instantly going to the washroom to puke (sorry that's gross!). For me now it's triggered by something stressful i.e. it happened every night after I saw my parents. Prior to my diagnosis it was happening all the time for about the last 3 months before my hospitalization. I was constantly nauseous and would puke before going to work. I assumed I just had the flu, but now I realize it was anxiety.

As far as questioning your diagnosis when were you diagnosed? Have you educated yourself on the illness i.e. read books etc.? It's natural and healthy to question it because this is your health and it wouldn't matter what I was diagnosed with I would research the s**** out of it to make sure the diagnosis fit.
