Dear Kitty,
                My onychophagia is getting worse. Today I managed to bite my finger so much that I bled for ten minutes and nearly fainted. I've done this since I was about six or seven, but it just seems to get worse with time! It's getting ridiculous at the moment.
                So I now have a plan. I'm going to copy Youtuber Beckie0 and buy myself a Tangle. They look really useful, and it's something I can fidget with during lessons because you can get relatively small ones. I think that I will order one after prep.
Failing that, it's back to the drawing board and five packs of gum per day.
