My username meaning is pretty literal. Back in March, my state implemented a mass quarantine, ordering everybody to stay home at all times, except for grocery shopping, medical care, walking alone outside for exercise, and essential jobs. The quarantine has no proper end date, and will continue until a Corona vaccine becomes available. This completely destroyed my will to live. I'm a very social person; before the quarantine, I had a rich, active social life, full of fun, lively outings with friends. Now, it's all been taken away from me, all because of a lousy flu virus. Multiple politicians tried to overturn my state's quarantine rulings, but they all failed. So I'd rather die from Corona, or CTB, than live under quarantine for the rest of my life.
So... if/when I CTB, my state will be responsible for my death, even if indirectly. Hence, my username.
