Help!! I’m a picker...

And I have no idea how to stop. 😭

First off I’m doing this anonymously because I’m so embarrassed. I have this thing where I sit and pick at sores and scabs. I can seriously be telling myself not to but can’t make myself stop. I think it may be a stress thing as we are going through a lot right now. I mainly pick at my shoulders and face. Anyone been through this? Any ideas why or what will help? I know it seems like a simply problem but for me, it’s just not.
