My nails are getting too thin.

Once you get your nails done, I feel like you keep doing it.

I kept doing it because I enjoyed looking at my pretty nails, but at some point, it felt like my nails were gradually getting thinner.

Sometimes my nails would break, but I didn't think much of it; it seems my nails were actually getting worse.

I'm not sure if it's because of my nails, but I've made up my mind not to do it for a while.
