Just wanted to drop you note about MS. My Mom had MS, my aunt (my Mom's sister) and now my sister has MS. I'm not sure where you live, but my Mom qualifed for PAWaiver program. It was a God send during her last 3 years (she was ill on top of her MS). We had a physical therapist come to the house and my Mom's MS was actually getting around better than she had in 20 years. My Mom's sister has progressive MS and can't do anything for herself anymore. My sister had 3 attacks last summer that were pretty serious but has recovered. Just to keep a person with MS motivated and upbeat is awfully hard so my thoughts and prayers go out to you as caregiver. Also give you local MS society a call and they should know what you can apply for or what's available.
P.S. I posted this note on the wrong person originally, still learning my way around the site. Sorry.
