when I get nervous I tend to bite a bit of skin off my lower and upper lip, crack my finger nuckles, sometimes my toe nuckles depinding if I'm home or not. I also ckracck my neck but i usualy sweat at times too I'm really really nervous

I have a tendency to suck on my index finger when I am nervous or chew on something. I figdget too. Its rather embarrassing.

When i get nervous i tend to bite my fingers to the point that there are catalysis on my fingers, a bit damaging to my fingers!

I just realized that when I am nervous I get really quiet and jittery. My coworkers say it looks like I drank two pounds of coffee!

I also tend to get really easy to startle and I bit my fingers. Not my fingernails, the skin NEXT to the fingernails.... not fun...
