How long ago did you do this? If it's only been a week, you're amazing to be doing some of the work you're doing from home. I know how you must have felt about your iPad. When I fell, I saved my laptop, but then all I could think about was not being able to ski. I vacillated between the pain in my leg and the pain of not skiing, sobbing for both.
Your fall sounds horrific! Very scary!
HR is taking you for granted, I'd say. I did a lot of work via Skype and email. I'm going back tomorrow. I hope I don't crash and burn before the day is over.
