New to the site-need advise

Hello everyone, I'm new to the site and wanted to get some advise over my skin picking. I'm 19 and I've been skin picking for about 4 years now. I mostly pick at my face, sometimes my chest or legs. Sometimes my picking is tolerable but lately it's been really bad. I recently was on a new medication for my depression, BDD and anxiety and I thought it was helping but then I realized I was getting more acne. When I get more acne I pick a lot more so I went off the medicine paranoid that it was making everything worse. I am now off the medicine and I am still getting acne and picking a ton and I feel even more depressed than I was on the medicine. In the past I've tried many things to try to stop the picking. I've worn band-aids and liquid band-aids on my finger tips, I've put up signs, I've worn gloves around the house, and I've even had a sheet over my mirror for about a year now. I have a small mirror in my bathroom that I use for my makeup but I always end up using it for picking. I can't stand living with this any longer. I always feel so ugly and I can't look at myself or leave the house without makeup on. I hate the way I look so much and I know that it's my fault. I don't know what to do to stop and at this point I just feel hopeless. I feel like I'll never really truly be happy with myself unless I stop picking but I don't know how to stop. I have some friends with anxiety and depression but I don't know anyone with a skin picking issue so it's hard for me to relate and talk to people. All my family just tells me I need to stop but they don't understand that I can't. I just need some advise from people who actually understand what I'm going through.
