stop biting my nails

I am pretty much starting over…..
My mom had a procedure done on her heart and I was SO worried that I bit my nails off. It is weird because I usually don’t bite my nails when I worry, but I did this time.
So I am starting again.

It has been about three weeks since I bit my nails. My two longest ones broke off. But I still refrained from biting them. I think that is why I usually get discouraged, because they break so easy.

I have always had a problem with biting my nails. It is not a nervous habit or anything like that, I just do it.I don’t bite them so bad that they bleed or anything, just bite them down short.
I have not bitten them in like a week and there are a couple that are getting long already.
My problem is…..my nails are very thin and weak, so they won’t get extremely long anyway. Anyone know anything I can use for that?
