Dana - so sorry you had to join us, this is not a "club" for the weak. TPFs tend to hang out in the Bone Breaks around the knee section - http://www.kneeguru.co.uk/KNEEtalk/index.php?board=21.0
There's a lot of information and support there. You might also want to check out mybrokenleg.com. Another great support group.
On of the things this injury does it makes us dependent on others, this is especially hard on those of us who always took care of others.
As far as your OS visit - write down any questions before hand if you can, take someone else with you to write down the doctor's answers. May sure you understand your doctor's orders regarding weight-bearing.
This is a rough injury to recover from, but many of us are back to our normal activities of skiing and biking. For me I'm in better shape now than I was before due to all the PT.
Good luck on our appointment
