Tar Disease

A fictional disease in where the subject bottles up negative emotions for too long, causing the subject's eyes and mouth to fill up with a tar-like substance until they either suffocate or tell someone their feelings.

The Tar Disease was dangerous, she knew that, but even as she tried to reject the sticky fluids filling up her throat, she knew she couldn't release her feelings for everyone to see.

He wiped the tar dripping from his eyes as his vision clouded.
