Mom needs support

I'm a new member, just joined. My daughter is 8, and has been pulling out her eyelashes for a year. At first I thought it was allergies, or itchy eyes. I took her to a pediatric opthamologist who said there was nothing medically wrong with her eyes. He said maybe it was triggered by itchy eyes, but turned into more of a "neurotic tic". I've also taken her to her pediatrician who told her to "try to stop" and try using a stress ball instead. For the past year we've just kept on eye on her, and had her wear gloves at night (which hasn't helped.) As soon as the lashes start to grow back, she pulls them again. Two days ago I noticed two bald spots on her head. I've just scheduled an appointment with a child pyschologist. I'm upset and wish I knew how to help her. I know she wants to stop. She's told me that she's "really mad at herself". It breaks my heart...
