Advise for a worried and worn out mom??

My daughter is 11 and looking back started pulling eyelashes around age 7. She now pulls her hair out on a daily basis and at the beginning of the year was almost completely bald. It grew back in a bit but she’s started again over the last couple weeks and is very thin again and bleeding sometimes. I am at a complete loss with what to do to help her. She wakes me up every night because she is pulling her hair out and sore or bleeding and she doesn’t trust herself to be alone anymore. She’s extremely anxious because of the pulling and unrelated to that has been a victim of bullying at school and missed most of this school year. We are in some counseling (just getting started as the wait list for services is horrendous) but knowing she has appointments makes the pulling worse. I don’t know how to help her work through what she’s feeling. We’ve tried so many distractions and fidget toys and reminders. We are both exhausted from not sleeping and she has not really left my side in over 6 months. I am one very worried and exhausted mom who just wants to see her beautiful daughter smile again and be happy. Any advise would be so welcome.
