Sorry to hear that.

I hope you heal faster than the 3-4 months.
I love biking too, so I feel you.
Is there a way for you to get outside and move around? Crutches could be a pain, but p00dlez's idea of a scooter is one example of what you could do if you wanna go out and about.
I definitely think you need to get out somehow because i can tell that you're going stir crazy when you're stuck inside. I'm just not good with suggestions, so I'm sorry about that
