First of all, you clearly have no knowledge on these illnesses in general, let alone any specific information on her actual case and situation, so making all of these claims that her illness is the most severe case of rheumatoid arthritis ever doesn't make sense, and you wouldn't even know what that looked like in the first place.
Scratch all that, what the hell are you even doing here? You are trying to equate a manageable chronic illness that was caught extremely early to a BLOOD CANCER WITH A 30% SURVIVAL RATE.
You do NOT need to go this far to defend the video game player/team you like the most. This level of parasocial behavior is super weird and unnecessary. It is NOT a big deal if videogamer Demon1 doesn't win as many videogame matches as before. Grow the hell up.
