So, I’ve been really bad at picking at my nails lately. I’ve always had a pretty bad habit. And I don’t just do it when I’m anxious— I do it when I’m bored or just need something to do with my hands. But like I said, lately it’s been horrible. It’s gotten to the point where, when I pick at my cuticle on my thumb, some of the base of my nail comes off. It hurts a lot but at the same time, I can’t stop picking at it. I’ve done this before to my opposite thumb but it’s almost healed/grown back all the way. I don’t want to do the same thing to this thumb too but I can’t help it. I’m having to treat it with hydrogen peroxide and neosporin and a band-aid everyday, like I did with my other one. I really want to break this habit. Does anyone know any safe alternatives to this? 

TL;DR: I need recommendations on safe alternatives to picking at my finger nails. 

Background Info: I deal with diagnosed depression, anxiety, and post traumatic stress disorder. I also think that I might have ADD but it has not been diagnosed.
