Any tips on how to not chew your lips?

I have anxiety and chewing my lips bloody is kind of a release for me... helps me think, gives my ADHD something to do, etc. I’ve done it my whole life but in the past year it’s gotten bad and my lips have started scarring. I don’t know how to stop! I used to have beautiful full lips and now they’re constantly cut and bleeding. I’m almost afraid to stop because then my energy doesn’t go anywhere and I start getting frustrated and feeling like I need to cry or am gonna explode
