Dancer, I’m afraid I can’t give you any advice on this. This is a tragic story, especially because your SIL has MS. I think Dianne is the best person to consult.

Just from my gut feeling, I would say the only thing you can do is help your SIL help herself. I’m not sure, but I think I once read or heard that MS victims get lethargic about their lives, so she will need tremendous support. She has to act now, as long as she is still able to. The longer she waits the more difficult (physically) it will be for her. But I’m sure you know this anyway.
