Pulling out hair as an adult

Does anyone else do this? Ill just be sitting there and I pick at and pull out strands of hair. Been doing it for years. Not stressed or anything. I do have anxiety but I did it far before I had anxiety. I didnt notice any hair missing until I got my hair cut and my grandma asked if I tease my hair because theres short chunks.... 😳 Im about to be 28yo.

Idk why I do this?! What can help me?
