Severe Toe Picking

I've always picked my nails, since I was little. Then in high school I started to pick the skin around my nails. It started to get progressively worse. I picked my toe nails too but not that much. A few years ago I started doing it even worse by using a thumb tack. I pick any nail or skin that is out of place or that I feel would be satisfying to pick. Sometimes it gets really painful but I'll keep going because I just need to get this one piece off etc. I don't do it for the pain or to purposely harm myself. I have diagnosed anxiety and ADD, not sure if that has to do with it. Anyway, there have been countless times where I will want to pick it so bad that I start bleeding, or I hit a nerve in my toe that I can feel at the start of my toe. I am getting concerned about this habit more-so because of my mental health. I don't have OCD (as far as I'm aware) but this is the #1 thing that I obsess over. The second I see my toes with any dead/hard skin or a loose nail, I have to pick it and then it leads into more depth and then I keep going and then I realize I have been doing it non stop for over an hour. Not sure if anyone is the same way or knows why I do this or what it is?

If you didnt notice, my big toes are completely round. This is because I never had long enough nails to properly shape my toes as I was growing, so they grew like bulbs...

Also, a couple years ago I had a procedure to remove the sides of the nail and root of both my big toes because they were ingrown. However, this was genetic and I picked before that. My picking really escalated months before the procedure when my toes were infected because I tried to pick off the ingrown part my self and along with that came picking every other part that was out of place too on my toes (on and around my nails).

Thanks for reading, I know it may be disgusting but this is the TMI group and I'm hoping maybe someone can relate to me or have suggestions.
