Hope that the blood test goes ok though I guess you then have the anxiety of waiting for the results.
It could be that your B12 is a bit low as my anxiety levels get higher when my B12 is low - and then I get through more B12 dealing with the anxiety - so bit of a vicious circle there.
Yes I thought the same as Gambit, you are worried about your blood test most probably..hope its gone OK for you.
I get a similar symptom. Heart racing panic attack and breathing heavily just after falling asleep but when I take my pulse, it is normal. I think it is something like vagus nerve damage providing false feedback to the brain.
Getting a grip on reality - as in taking my pulse in my case - I think reassures the brain and slow the flow of the chemicals (adrenalin?) so I calm down.
I think this symptom occurs more frequently if I've had too much folic acid or the balance between folic acid and b12 is tipped to the folic acid side.
I also find increasing the acidity of my stomach as in drinking some orange juice also helps calm things down.
