I think famous people die this way because they lose who they really are for what is temporary. It looks good all the fame and money but the truth they are empty inside. Before she died you never heard her music played and now you hear it every where. When you are down on your luck the people in Hollywood only talk about you in a negative, they do not come to help lift you up. But the moment you die they act like they were your best friend.
Take Don Cornelius he was ill, but I do believe he was lonely and longed for those in hollywood to come see about him. They probally did not want to see him in the condition he was in so they stopped coming and calling.
I won't get all bible but when your only spirti is other people faith in you and you lose it you are all alone. But when you have faith in God and can call on a higher power no one can take your spirit.
