I just need some hope

Hi everyone. So I've been picking at my skin for a good 5 years now and have the scars to prove it. I have a question about the last mistake I've made. There was a zit on my neck that I kept picking at and it left me with what looked like an ulcer. It looked so bad I thought I might need stitches, so I made an appointment with my dermatologist. When she looked at it she told me I was over reacting and that it should heal. But there is literally a crater in my neck, it looks like a cigarette burn. She prescribed me Bactroban, which I have been using and it did help it heal faster, but yesterday in the shower, the scab that had formed fell off and now here I am with a crater yet again. However, I noticed that in the center of the crater, there is this white, grainy/flakey looking skin. I'm still putting the ointment on the wound, but do you guys think that since there is that white gainy/flakey skin under the scab that it means the lesion is still healing and that my crater *might* fill in? I just don't know at this point. Sometimes I've had indents fill in and other times they don't and I'm left with a crater. I just hope this grainy skin under the scab is a sign the wound is still healing and filling itself in. What do you guys think?
