The compulsions are ruining my life, help

(Bandage on image 2 is unrelated, cut by a plastic jar lid)

Hey everyone, first post here.

I've had a couple of compulsions on and off for years now, from peeling split ends to lip picking to eyebrow/lash plucking. The nails, however, are something else.

If I'm not nipping them, I'm picking them, and it doesn't matter if they bleed or how painful it is. The compulsion simply needs my nail skin to be perfectly smooth and soft, which obviously doesn't happen since it grows back even thicker than it was before. I'm wasting upwards of an hour nearly every day just maintaining this compulsion, and all that lost time is another hit to my already-suffering grades (thanks, undiagnosed ADHD). Also the red spots in the images above are constantly raw and tender, probably extremely prone to infection considering I keep reopening the wounds there.

All this to say - I'm in need of some advice. Where do I go from here? I'd like to keep new purchases to a minimum but if there's anything useful that you'd find in a typical pharmacy, feel free to suggest.
