so tired of picking, its really interfering

Not sure what to do anymore, my back has never looked this bad, even if it is clearing up i cant even tell because of all the scars. havent worn a tank top or anything showing my chest or back in the past 5 months. my chest also has permanent holes in it from picking, even my breasts. my shoulders are horrible. i have holes in my face that look like chicken pox scars but there just from picking, i even have a scar under my eye that puffs out instead of in, which makes my eye look baggy. my forehead and cheeks havent been clear in the past 5 months. more and more holes are being made, these arent just dark scars, there actual holes. i constantly feel itchy and dirty which is why i pick the scabs over and over. havent gone a day without picking in i dont know how long. its now been about 3 and a half years since ive picking my face, chest, back, legs and everything else. except been picking my scalp for 9 years now.. i would like to get help from a psychologist or something but definitely dont have the money to right now. i used to have such a nice back, now its completely ruined, it looks like i have chicken pox. where to go now....
