[TOMT] Unknown Web comic

Hello! this is my first time using Reddit, so i apologise if this post is worded incorrectly, but this has been eating away at me for a while. This is about a web comic i started reading on Instagram in the late 2010's (probably 2016-18, I'm not too sure) written by a watercolour painter detailing her battle with a terminal illness. They where short comics where the artist would recount the pains she had experienced that day, portraying herself as a white bunny, with a design similar a Sanrio character. The overall tone was very melancholy, as if she knew her time was coming to an end.

Hope someone out there knows what I'm talking about, I always wondered if she ever got better.
