I have been driving myself nuts these past few weeks with my fingernails, obsessively feeling the nail with my lips. My husband has really noticed and it's getting on his nerves too. When I was a child I would chew on my nails. Eventually, I started cutting my nails really short so I couldn't chew on them. Then I started to feel my nails with my lips and ever since I have done so. It's better for my nails but I'm definitely anxious, probably about my upcoming c-section.
