Sorry to hear that, hope you get well soon.
First off, i shoot in M and been doing so for the past 7 years, even with 60D and 1D. I learned to take it slow and look for what i want to capture. M slows you down... no 6fps or P or A.
Secondly i adapt to my camera and lenses, i read the manual and try everything so that i know my cameras strenght and weakness.
Third, i learn what i can and cant focus on, you need contrast differences in your subject.
The AF speed is not the issue (unless it's fast moving objects) but locking the AF is...i have a few hit and miss here and there, but nothing that dident happen on my Canons with L lenses aswell.
My #1 tip is to never compare a camera,sure compare lenses, but instead learn to work with what you have at hand.
