Oh GLC...this sucks. I've recently been through a non weight bearing experience. I wasn't sure at the time that I would live to tell about it but I found out that IT DOES GET BETTER

You've already gotten a lot of good advice. Here are a few other things that I wish I had known before my experience with crutches:

I didn't realize how quickly muscles atrophy from non-use, or how many muscles would be affected. I wish that I had consulted with a physical therapist every 1-2 weeks while I was non weight bearing. A good therapist would have anticipated which problems I might experience and could have given me home exercises to maintain as much muscle, proprioception, flexibility, and motor control as possible while still protecting my injured limb. I probably could have avoided several problems that took me months to overcome had I not waited until I got out of the boot to work with a therapist.

I wish that I had had a stable walker to get to the bathroom in the middle of the night, even if I didn't use the walker for anything else. Crutches were OK for the first few weeks but I became increasingly unstable in the middle of the night as the weeks wore on. I now suspect that much of the instability was due to core muscle atrophy that I didn't realize was happening.

Most importantly, I would not have filled my down time by reading internet horror stories about people who were having trouble recovering from an injury similar to mine. Those stories scared me silly. I didn't stop to think about the majority of people who healed well and didn't have time to write about it because they had gotten back to their normal lives. I would have spent less time Googling and more time asking questions of the healthy, positive, people on TE. You're on the right track by posting here
