If you're mentally ill, chronically ill or otherwise disabled, do yourself a favor and consciously work to dismantle the "if you're too sick to go to work you're also too sick to be on the computer" mindset which got drilled into most of us during childhood. You don't have to deny yourself joy. You don't have to directly or indirectly punish yourself for not being able to do certain things. It doesn't help anyone. All it does is make you even more miserable than you have to be. So make sure you don't punish yourself for being sick. Make sure you don't subconsciously sabotage yourself with the idea that you have to be punished for not being abled. Make sure you embrace the joy you can find instead of denying yourself out of unnecessary guilt.
I've seen the shortened version of Cab Calloway's St James Infirmary Blues from the Betty Boop Snow White 1933 cartoon on Tumblr a few times, thought you'd all like the full version.
