I don't know what to do!

I have been picking for almost 2 years. It started when I went to college. Every zit I get I have to pick at and it leaves big wounds that take forever to heal:( I want to stop picking and I welcome any suggestions on how to get a wound to heal faster! I've had a big wound for almost 2 weeks & it hasn't scabbed or anything because I keep putting lotions on and then during the day I take off the lotion or Vaseline that I was wearing overnight & put makeup on. So it's drying out during the day and moist at night! I think the best way for it to heal is to leave it alone. Suggestions welcomed!
