I hate it, but can't stop myself

I'm a 24 year old female. From preteen age to now, I have been a severe picker. I remember kids at school would comment on how bad my skin was and although I knew it was the truth, I would and still continue to torture my once pretty, olive complected skin!!!! Night time is my enemy...I go into the bathroom, sit on top of the sink area, and go to town on my poor face! Tell me, how can I stop this ritual?! any advice would help...I'm trying not to pick for a month..tonight is my first night...I also am trying to avoid the mirror unless it's to do my hair or beauty rituals. Thanks for reading!
