My 'collecting' only makes me worse (scabs)

For several years now, I've been collecting any scab I pick off. I know collecting them is really weird and is only making my picking worse, but the thought of getting rid of them distresses me greatly. Not sure what my point in posting this was, I guess I just didn't want to hide this anymore.

I worry a lot about what people close to me would think if they knew. I've kept this hidden for so long, just wanted to get it off my chest.
