New member!!! and Any tips for a non painful shower?

Hey guys, I'm brand new to this site, I didn't even know that there was a name for what I do (dermatillomania) or that I'm not the only one who does it so discovering this a couple days ago was amazing!! So I haven't showered in a couple of days because I picked 2 spots and got pretty deep and I'm sure as you know showering with this shit stings like hell! So I was going to shower tomorrow which would have given them some time to heal to reduce the sting but of course I just picked a new spot deep and I have to shower tomorrow. I feel gross and have work and my sisters birthday get together so I don't really have a choice. So my question is -- does anyone how to reduce the sting in the shower from water/soap? I've tried bandages but they fall off after a minute or 2 or get water under the bandage. I've tried layering bandages and that doesn't work either. So maybe there's something I can do without bandages? PLEASE HELP!!!!!
