[TOMT] Late 90’s early 2000’s animation/ music video

I vividly remember this music video or animation from the early 2000’s with a creepy vibe to it like 3d animation, with the main character being a little guy looking for a disease that i think is going to eventually kill him. The video seems post-apocalyptic with this disease possibly killing everyone else. The beginning of the video shows this guys house that is way up in the air connected to others with rope? and those wood and rope bridges. It was very dark throughout the entire video and i think the guy was looking for a cure to whatever this disease was. I remember him looking at the little microbe or whatever disease under a microscope, this was inside his house that was up in the air. I feel like it had to be a metal kind of song in the background. I cannot remember what song was with it but i FEEL SO DEEPLY that it was or was adjacent to Numb by Linkin Park.
