Hi, I am Kathy, I have been disabled for a very long time now. The best I can tell you is to try to concentrate on what you can do not what you can no longer do.
I hope it does not sound like this is simple, its not, in fact it is very difficult. But with time and help from others you will find that what your life once was will never be again, but you still have a life. Concentrate on the life you have. Again, its not easy, not at all, it might be the most difficult thing you have done, but you can do it.
You will know, because you will find it easier to get up, you will find yourself smiling more. It will not happen overnight, but it will happen if you allow it to.
