Growing up I always bit my nails until I got my braces. After that, I stopped. But I now have turned to another habit which is picking at my lips. It’s gotten worse over the years to the point where I make them bleed. I usually do it once daily and I don’t notice till my mom yells at me. This is making me feel ashamed and I have to make up an excuse for my boyfriend to not kiss me. Is this normal or is this a sign of something else? A mental illness maybe? Depression “runs” in my family and both my mother and grandma have it. Or it could be social anxiety which is something I think I may have. Thank you.
