Oh, my goodness! All those seizures? I think I would ask about that medication that Robin mentioned. She's been there and done that. I know I hate Prednisone. I had to take it for Crohn's and also my auto immune inner ear disease and it caused more problems than it solved. But you should touch base with your doctor and mention this medication and see what they have to say.
I'm so sorry you are having all these issues. It sounds like you are handling it with grace...just like Robin does. You two are an inspiration to me.
