<human>: This isn't life threatening or severely urgent, but I would really appreciate some ideas from fresher minds. I also want to start off by saying I'm still getting the hang of posting things here, especially through mobile, so please be lenient towards my lack of know-how. I'm 19, sleepy, and technologically challenged.
Anywho. My significant other has bad anxiety. He doesn't voice his worries or even act worried in many ways. To most people, he seems very happy-go-lucky. But I see him. He takes his anxieties out on himself physically. There's no thumb twiddling or worried glances, no- there's chewed off nails and holes bitten into his lips. He has scars on his finger knuckles where he's chewed his skin to the bone, and the knuckles of his toes are permanently brown and purple because he kicks walls so visciously, he's damn near broken his toes. It always looks like he has oral herpes because he chews at a spot on his lip, and on ocassion he's gotten a little worse and pulled out hair. 
Any advise on how I can help him relax or slow down? Or any way to get him to break his habit of knawing on his own finger flesh? It doesn't necessarily seem to bother him, but I worry that one day he won't realize what he's doing until he's really hurt himself.

Could you distill the essence of the text into 1-3 sentences?
