Thumbsucking

Last week I got a blister on my thumb from videogames, which resulted in a pea-sized hole where the skin peeled away. So over the course of the week I couldn't help nibble on the frayed ends and wondering when it would stop. And now it's smooth on the edges, but I can't stop putting it in my mouth because the new skin is so smooth it's a really weird feeling on my tongue. I know this is weird.
