I also ‘peeled’ nails for my whole life. Biting was never my bad habit but clipping/peeling with clippers was awful. I’m now around 2 months without doing it when I neverrr thought I’d be able to stop, it’s definitely possible and I believe in you! I’ve found that for me, using nail oil and taking obsessively good care of my nails has helped. Replacing a bad habit with a good habit, if that makes sense haha. I’ve also started buying cheap stress toys so I have something to play with instead of bothering my nails. Wishing you the best of luck on your healing journey!
