You shouldn't feel you need to punish yourself, talk with someone here, pm, one of us if you want to talk about this.
Skin picking and scratching can stem from a habit in some people, often with an origin of stress, etc.
Therapy can help unlock the reason behind such actions, and then work through this.
Just my 2 cents.

Please take care now,
