I’m 24 & have a 6 month emergency fund. I have diseases that will likely make me die before 65. Why not throw half of that into TQQ?

I feel like I have nothing to lose. My family would help if I needed a surgery/treatment sooner rather than later but that’s not likely (knock on wood).

TQQQ is down 40% this month. 34% in the past 365 days.

The supply chain is finally improving, market sentiment is the lowest it has been since March 2009 (the bottom of the great recession). I feel like the market cannot get significantly worse from here. Am I crazy for wanting to do this given my situation?
