This helps

I know that this is the hardest thing in the world to do right now, but exercise, exercise, exercise.  I am strengthening muscle groups that have not shut down.  I can't stress it enough.  I have a hard time standing up from a chair, so that is my first exercise.  Just stand up from a chair.  You don't need weights or machines, just try and do the things that your body is not allowing you to do over and over.  Exercise does make me want to pass out, but that is when I know that it is time to quit, and if you are standing, make sure that there is a chair behind you to catch yourself in.
