Yes - I am hoping that she has a few more people around her (close friends and family) who don't want to be on camera, because it did appear that apart from her children, she only has paid staff in her life.
I also think that she is struggling so badly because she can't really leave the house now, and doesn't see many people. And she was previously someone who regularly travelled the world, mixed a lot with dozens of people, and had a wide circle of friends.
She is basically trapped where she is, in that big house, with very few people in her life. Her health is holding her back, because she doesn't know when she will have a seizure, and she is wobbly on her feet, and prone to keeling over...
She clearly loved the audiences, the fans, the adoration, and the attention, and she was at home on the stage, and is devastated to have lost her singing voice... That was the one thing that was so very special and precious in her life (apart from her husband and children,). She seems quite depressed now. Poor love. 
I also think that when she sang that last song - 'This Is Who I Am' I think it was called, it sounded nothing like the Celine Dion I have known and loved since 1991. Very sad. 😢
