I understand how you feel. For several months after my fall I just kept on hoping to get back to my old self. One of my biggest turning points was when I let go of that. I did that with the help of a meditation series called perfect health by deepak chopra. Also, one of my friends said that she liked the new me better. I then started to think about this as an opportunity to start fresh and create a new me. I now can say that I also like the new me better. Have I been through horrible pain and suffering? Yes! But hopefully I'm coming out on the other end having learned some important life lessons. This injury has really slowed me down...but I think that's a good thing.
Try to love and accept yourself with all of the changes. Try not to think about the things you can't do...but maybe cherish the things you can do and find a few new things to do.
Good luck
Su
