Even though you are just biting at your fingers it could escalate. Picking and biting your skin is along the same lines as cutting. It's a form of emotional release. Medication and therapy should help along with some of the other suggestions offered here. You could try keeping lotions on your hands at all times to want to avoid sticking your fingers in your mouth but this probably won't stop the urge.

Although, it's nothing to be embarrassed about, keep in mind that doing these things will cause permanent scarring. I have a friend who has done this and has scars all over her arms and legs. This may be a deterrent if you find it embarrassing. Good luck to you, dear.

Something hidden eating away at you. You can get help by talking it out with a good therapist. My ex did that a lot. It won't stop till you deal with it. Hope this helps.

The rubber band thing didn’t work for me... I couldn’t get it to snap hard enough to make me want to stop. I do recommend the Pavlov shock band! It helped me a lot with my sleep ( I have a lot of trouble waking up in the mornings) they have a Pavlov 2 wrist band that’s for breaking bad habits. It has different levels of shock but let me tell you .... it hurt me and I wasn’t at a high level

It sounds like maybe you have some bad anxiety...? Can you take any meds for it? I use to pick my skin some but my problem use to be I twirled my hair into big knots on my head. That’s how I would cope with things. I started anxiety meds and it stopped. NOW I do something even worse tho I grind my teeth and rub my tongue along the bottom of my teeth! It’s a side effect from another medication I am taking not anxiety.

Thank you. I will ask about it
