And the timeline the doctor gave for when something could have caused the issue lines up with the illness you got from the person who ignored your request to be careful. And it can't be confirmed but it is eating me alive.

This is especially true if they politely asked everyone to be extra cautious and not come around if they've been around sick people and you decided to ignore that. Signed someone who begged people to be careful and then gave birth to a kid with lifelong complications.

Even if you think every school aged kid will be fine if they get sick, so many have newborn siblings or elderly grandparents.

Absolutely!

I feel like the most punk rock thing is to simply make "bad" art that you get something out of the process of making rather than stealing other's work while having no process or experience at all.
