I'm the same way. I pick at everything. I bite my nails and my cuticles. I often pick at things without even thinking then realize I'm bleeding. My boyfriend gets upset and always grabs my hand away and asks me to stop but most of the time it's subconscious. I'm on lexapro for anxiety but haven't noticed any changes in my OCD.

I guess I don't really have advice because I haven't found a solution either but just letting you know that you're not alone. I hope you can get help from someone.
