skin and face picking

Ok I just got to the point where enough is enough! I have prayed about it. Went online and learned my problem is an actual condition. But avoiding the problem isn't working. my boyfriend is still telling me at least 10-15 times a day to quit picking. I can't do this anymore. My arms used to be a major problem and i stoped some how. Maybe a good month with my nerves or something, i don't know. My hands were pretty bad and i was able to stop until today. I didn't do a lot of damage but its not the point. I see a bubble on my pinky fingers, both, and boom! i pop them. I stoped myself before it got to bad because i felt horrible. Why can't i stop picking my face then. Its the only area now i need help with. Even when i stoped picking my arms, and hands, i still have my face thats being picked. I don't know why i do it. i don't know why i can't stop. Please someone help me. I need a new method that doesn't involve prescribed drugs, therapist, whatever. I need something that i can do on my own to help myself. My boyfriend can't help me, that is apparent. I can't keep doing this to myself and him. Please help me!
