Specifically eyelashes and eyebrows in my case. 

I've been struggling with it since maybe like 11 years old, now 21. It happens when i'm stressed or bored. I'm less aware of it when i'm stressed and don't notice it until afterwards. It feels like i'll get release but i know that's hardly true and it leaves me stressed out about my appearance, which can make things worse. 

I'm waiting to see my clinical psychologist soon, but just looking for something in the meantime by someone who understands. I hardly remember discussing this in therapy in these years as bipolar and ADHD were the main pain in my ass, they took preference. Bipolar is under control, now ADHD and anxiety is turning into my main concern. 

Any suggestions?
