Phew what misery! I can imagine you should feel pretty disabled when you can only use 50% of the power in your hand, not to mention being extra carefull not to harm your pinky finger again.
Tomorrow when I sill grab the handrail of the stairs at work, I will be thinking of this story!
Two things really made me feel disabled: cutting meat (very hard to hold the fork) and typing. I didn't think I used my little finger much for that, but it became very difficult and I made (actually still make) lots of mistakes. When I had the cast on typing was so slow I investigated Google Docs speech to text - very impressive.
Nice! That is how something good can come from something bad like this! :-) hope you re 100% soon!
