Do you have any habits that you go to when you are nervous? For example, when I get nervous I have to crack every part of my body. I also bite my nails, not just my nails, but destroy my cuticles. I guess the slight feeling of pain relieves the stress? I have found ways to prevent it by wearing a hair band around my wrist and snapping it instead. Do you have any nervous habits? And if so, how do you deal with them?
