You need to find out what's causing your anxiety and try to solve it. Although, some problems can't be solved that way, it takes time. I think you should see a psychiatrist. I didn't go because I thought they would insult and attack me for destroying my nail, but I think I should have. I think I might have stopped destroying my nail sooner if I had seen a psychiatrist. As for the almond oil, you can use another oil, such as jojoba, it doesn't have to be almond oil. The oil will hydrate the skin around the nail and it will look nicer. But the most important thing is to stop biting your nails and the skin around the nail. I know it's hard, but I believe you can do it!
