Best picking position for ergonomics?
So I've recently been laid off and have a lot more free time so I've really dived into picking as a way to occupy my mind. I've been doing it for several hours a day for about a month, and I'm frustrated to discover that I've gotten repetitive strain injuries in my index finger, thumb, and a bit of my wrist.
This was my original position. The acute concave angle of my index finger from gripping the thin pick and sliding it back and forth strained the muscle I think. And the thumb at the base also, as I slid the pick back and forth across the tip of the middle finger. I had tried to approach the vise from the side so as to minimize the angle of the wrist, but it resulted in gripping harder with my index finger.
Next I tried approaching head on while keeping the index finger straight to prevent further injury, but this drastically increased the angle of the wrist which is uncomfortable, although even when I tried to keep the wrist straight I'm still experiencing aching in it.
So what position do you guys use? Do you slide the pick along your middle finger using your thumb and forefinger or do you move your whole hand as one unit? How do you brace the pick? What is your angle of attack? What's your wrist angle? Can you show pictures?
I'd really like to know how to do this without injuring myself, I'm very frustrated at not being able to do it for probably 2 or 3 weeks while I recover. I must be doing something wrong because people play piano and guitar every day for years without injuring themselves.

Thanks!
