Why do i pluck out my eyelashes and eyebrows?

Patient: It’s usually my eyelashes but sometimes my eyebrows. Even when I catch myself, I still want to do it because I impulsively do it. When I do it, i feel really relaxed after it and if i dont do it, tension builds up and i get so irritated that i keep doing it anyways. Im getting like bald spots on my eye and a little bit on my eyebrow. It feels like it itches or something and after I pluck, that itch goes away but sometimes it doesn’t and I pluck more. After, i roll it in betwen my fingers. It scares me and i wasnt to break this before i lose all my hair! Im 16 years old today.
