Hangnails and Lip Picking Issues

I am having issues with picking hangnails and my lips. I only pick my bottom lip until all the skin is gone and sometimes past that till it profusely bleeds. I am a 20 year old male and I can't control this problem. I do not know how to talk to anyone about the lip picking because I do not know if my reasons for it are weird, but it feels like my flesh underneath can "breathe" when the lip skin is off, like it feels so good when a breezes rolls past. My lips look so bad now and I do not know what to do about it.

I also have hangnail picking problems where I would pick the skin off all around the nail till it bleeds. It also seems weird to me because it makes me feel like my fingers are "alive" (like I feel them all the time due to the masochist pain methods) and don't feel them as much without. My fingers are all messed up too.

What can I do to stop? Should I stop if its a mental thing? Please help.
