Hey Word Girl-
Welcome. Your friend is really lucky to have you. The support team is so important to MSers...it IS an overwhelming disease. No one really knows what causes it or how to heal it. Many, many theories. Everyone's disease is different.
I'm also on the wet coast, (it's been hailing!) and very verbose. Keeping my husband (dx 3/07) healthy, I've learned so much on this site. Nutrition, attitude, exercise can all make a huge difference. Help your friend to feel more empowered, and less out of control. Support her decisions, keep her focused on the now, laughter, and what she can do for herself.
all the best,
