Does anyone have any tips for stopping yourself from picking scabs? Your own, not other people's

When my anxiety is getting bad, I tend to unconsciously scratch whatever patch of skin is closest. Right at the moment I have 4 decent sized scabs, 2 on my arm and 2 on my face. They're hideously attractive as you would imagine.

My problem is, I cannot stop myself from picking them all the time! Dressings don't tend to stay on me for some reason. I bought spray bandage, which hurts unbelievably when I spray it on, and while it frustrates for me for a day or so, as I can't get under it, I still work at it til I get there.

I'm not sure if these scratches would've left scars anyway, I already have 3 that have completely healed and they've scarred, but I picked them. I would very much like to avoid further scarring - any tips?
