Lixy, I feel for ya so much...sis' behavior sounds so much like my daddy's during his last few years it's not funny (not that it ever could be)...they diagnosed it as Alzeimer's, but I know for a fact you can't make a positive diagnosis until the autopsy, & none was done...a few months after his death, I read an article in some kind of newsletter I was stripping up (you know what that means I was doing LOL) that described the symptoms of Congestive Heart Failure, & about 90% of them fit...there are so many different things could up with sis, & at 50, I would think that Early Onset Alziemer's might be one of them...all I can offer is hugs & sympathy, & I think maybe the best way for you to get thru this yourself is to give BIL as much time as you can spare to talk it out, & that way maybe you can stay informed, & not feel so helpless sitting there worrying...I know you've got a full plate with Mr Lix, so be good to you as much as you can...
