It's possible that Ron, Henry and some of the other cast members have tried to help her; Scott himself mentioned not too long ago that he had offered to help her several times (I don't know if recently or in the past) and she rejected it. I think her main issue is not money.
Wasn't she writing a book a couple of years ago? Lots of actors from that era have released their biographies. A good book contract could bring in some more money, but then again, that's not her main issue.
Anyway, this is very, very sad. I hope she realizes she needs help before it's too late.
