(Star Tears disease - Similar to Hanahaki disease, instead, the victim cries stars until they eventually go blind. Similar cause being unrequited/one sided love.)
You had begun tearing up sometimes, although they weren't normal tears, Small stars came out of your eyes. Sharp stars, they hurt quite a lot.
You didn't want to admit you knew why it was happening, - you liked Alastor, a man who quite possibly, could not feel any romantic affection for anyone. Atleast that's what everyone assumes, from how reserved he acts over love.
It started small, with only the occasional star slipping out, causing pain, and you'd go on with your day. But, at this point. You couldn't focus, your eyes ached and stung, and even blinking rapidly caused a few stars to fall.
