I have noticed that it really seems to take a LONG time to come back from any sort of surgery or illness....Please be easy on yourself when recovering.  I am sure you've all heard: "It's not going to happen overnight." but it's true, and whatever progress you make, however long it takes to make it, and even if you feel like you're going 3 steps forward and 1 back, it's where you're at, and that's okay. Just keep trying to get better.  It WILL come!
