What are your nervous habits?

I have habits that I do when I’m nervous, which is all the time.

Do yall have any nervous habits?

In pre-K, I chewed on the insides of my cheeks. In first grade, I bit my arms and hands. Things like that.

My favourite one was when I would dig my fingernails into my arms to I could make smiley faces.

Now I have three habits. Ripping the skin of my right thumb’s cuticle, cracking my bones, and pushing my fingers against my lips and then biting my lips.

Now I’ve got another question, is it normal for my bones to crack this much?

I mean, I know I crack my bones a lot, but I got a bit concerned when I breathed in and my back cracked. I crack my bones around three times a day, I think, but maybe a few more times for my knuckles and a bit less for things like my shoulders and knees.
