Ah, I knew there was a reason why you couldn't run. I just couldn't remember. My apologies.
To be honest, I can't really give you an empathetic opinion. I've never been in a bad bike wreck so I can't grasp of the fear regarding your situation. I do know this though, I love riding and running and life wouldn't be the same without either of the two. If I were you, I would continue to ride like you stole the bike. Life as we all know, is too short as it is to not enjoy our hobbies.
Like skydiving. Which, I'm getting back into hopefully this fall.
