I'm pretty damn late reading this one. I'm really sorry to hear about your accident. I know you can recover. My uncle had a snowmobile accident where he smashed the middle bone in his middle finger. They said they could replace it with nylon bone and he'd have about 20% movement in the finger. He said, "cut it the F off". He's still one of the more hany guys I know. He even makes jokes like, playing hide and seek with his young son, he's told "no peeking", so he covers his eyes with his hand.... of course there's a gap to look through. It's funnier in person.
I used to work doing hot asphalt roofing. Asphalt is heated to 490 degrees F for application. The guys on the crew used to say, "the day that you stop being afraid of that black stuff (they used a more explicative term) is the day you need to quit, 'cause it will hurt you, or kill you."
Same goes for power tools.
I wasn't sure, did you loose your index finger and damage the middle finger? I was wondering why the middle one was pinned.
Oh, and the television series American Inventor recently showcased a contestant who lost his index finger. Maybe inspiriational.
