*TW* how to stop self harming?

I don’t cut. I think that’s the first thing everyone thinks of when they hear “self harm”.

Instead, I pick at my lips. It’s something I’ve done since I was in 4th grade. I got better for a bit, but recently it’s come back. It’s an impulsive act. I don’t know I’ve peeled off skin until it bleeds. I want to stop, but I really don’t know how. Does anyone have any advice?
