Hair twirling, constantly. Always touching my hair, running my fingers through it, trying to pull off split ends. People have pointed out the behavior before and it's beyond embarrassing. Putting my hair up works, but then I go off focusing on some other spot.

For the nail thing, I can't relate to actually picking them off, but I have dermatillomania so I'm picking skin instead. I had to give up on long nails. It got so bad. I need nail clippers with me at school, work, in my car just in case the destructive habit came back. But it's your decision whether or not you want to give that up as well, I know it can be difficult to sacrifice something you've been working on.

Honestly, I haven't found a good solution for the picking/pulling yet, but it helps to have something to keep your hands busy like a bracelet, or there's these things called spinner rings. If you can't stop the behavior, it's always better to redirect it somewhere else!
