I came across this cartoon in a post somewhere about goth-adjacent comics... I think it was started in 2013 and ran through the end of that decade... The artist later started developing another cartoon called Cats Cafe on Tumblr that ended up [taking] their time instead.
The whole MaryDeath series is pretty good, the site spews errors when I look at it day-by-day, but you can read the whole archive here: https://www.marydeathcomics.com/archives/comic/
The artist transitioned recently, but it seems they don't mind their deadname being on their older comics (i.e. their most recent Cats Cafe post has it.)
