As someone who has also had her share of accidents, injuries or illnesses and has had to be off the bike longer than expected or desired, I share your pain and understand your anxiety but... it sounds like you need to stay off, rest, and heal properly. Take up another sport. I started hiking again after my collarbone surgery (which btw was necessary because I did not let the fracture properly heal). Also I was able to do spin classes to keep my legs moving. The doctor and therapist are just concerned about you falling again and getting hurt further. Give it the proper time. You'll be biking soon enough.
