my nail-biting problem

[nelysses]

I've been biting my nails constantly since childhood. My blood tests are normal. My doctor said I have chronic stress, but honestly, I didn't pay much attention to it, etc., I'm skipping over that part.
I've stopped this habit a week ago. I don't bite my nails anymore. But the problem is that black deposits form on the tips of my nails and they never come off. Although AI says it's dead pigments and not dirt, it looks really ugly. My nail tips look black. Has anyone else experienced this?

You definitely have some stress or anxiety. Maybe you’ve got a dirty mouth, too; some kind of candida fungus keeping you anxious and are transferring it to your fingers by mouth.

Try researching or trying herbal supplements like ashwagandha or something to help calm down.

Dip your fingers in apple cider vinegar so every time you bit down you’ll be reminded of how nasty your habit is.

Wear gloves.
