I'm a high school kid who has experienced depression and is currently experiencing anxiety. You see, I used to have long, strong, thick nails. I was quite proud of them (mainly because they were my main self harm tools). But, due to anxiety, I started biting my nails down. Now, they don't even grow past the tip of my finger. I always keep them super short. I also bite off the skin around my nails, and try to tear away my cuticles.
