Mine have all been listed and it's a little comforting knowing that it's related and maybe once it's all under control I can get past these habits

1. I bite my nails, the skin around my nails and the scabs that form from prior biting on my fingers. I'm always upset by how gross my fingers look and I work in customer service and try to hide them when I'm giving change etc. I had almost kicked the habit in the spring but when I was going through the no income stress/new job stress I picked it up again. I've only gotten 3 nails but I've bitten around the nails on more fingers. It's frustrating because sometimes when I'm doing it, I know it, but I'm like stuck and can't stop even when I tell myself to
2. I scratch my legs. I have scars on them and they bleed sometimes. I have a physical feeling of being itchy so it's the natural instinct to scratch and it doesn't go away so I keep going
3. Grind my teeth. I do it in my sleep and when I'm awake.
4. I roll my neck. I say roll because I do it more than I can actually crack it
5. Fidget my hands. At the doctor or T when I'm talking about my anxiety I constantly roll my hands around each other. I wiggle my feet a lot too.

I feel like I have so many of these habits I can't replace them because it's just such a huge task. On a completely random note, I was literally just about to post something like this, so thank you for doing so
