I think you need to heal emotionally as well as physically. Even though for me a great thing happened, the isolation you feel after, along with the amount of time without any activity that you're used to can take some getting used to.
I also had to rearrange myself mentally. I had given up on certain activities in my life, and now was planning on resuming them. The lack of mobility, even going out on crutches can be a bit embarrassing until the time is done.
Patience I think is the key here, patience with the process, but also with yourself, since you are going through an emotional time. Just remember that you are limited for a tiny amount of time, but will be freed of the pain that has sapped you for the rest of your life hopefully.
I had something happen that was great. I was carrying something out of the car, and dropped a couple of things. One went under the car. Before the operations, that would have been a gateway to hell, since I would had needed to find a way down (in pain), reach under the car (in more pain) and get back up (excruciating). Now I just knelt down, reached under the car, got it and stood up. I didn't even notice the difference until I started walking away. Little things like this helped me keep positive as I recouped.
