Bad habit of reducing healing itches by cutting on top of the itch. Help?

I'm so itchy dude. Obviously. Even cat scratches are a pain in the ass to heal from because they're so itchy. It hurts when I scratch the itches myself, so I've resorted to just cutting where the itches are. Which obviously results in more itching. What do you guys recommend I do? Just ignore it? But I have cuts all over my body, it's almost inevitable that I'm going to cut across another cut anyway unless I don't cut until they scar/go away... which requires too much patience. But god dude I'm itchy, and I'm just making wounds bigger by scratching them open with either my hand or my blade.
