It's good her grandmother is moving into palliative care. Even if Chantal wasn't too fucking fat, lazy, and clueless to be of any help to her mother, it sounds like things would be beyond their ability to manage. And it's much worse when you're family, due to the emotions that come up. Her mom's made an honest effort, but this is just too goddamned hard. And Chantal is no fucking help whatsoever, and probably of no comfort. So as shit as the situation is, sending her to palliative care sounds like the best decision.
Chantal is lucky that she hasn't yet had to deal with death in her 36 years on this planet--most of us have lost at least one grandparent by that age. But she also hasn't had close friends who have suffered those kinds of losses, so I don't think she's ever had cause to think about what it would mean when her time to face death came.
She isn't even remotely prepared for what's about to happen. She still thinks there's a chance her grandma will "get better," and thinks "palliative rehab" in this case is rehab--not hospice care. Part of that is because she's dumb and clueless, but a huge part of that is also denial, and shit's going to get ugly when reality finally breaks through.
I'd feel bad for her if she didn't feel she had to take to YouTube to share all the details of her grandmother's condition, and talk about how traumatic and hard it all is for her. She said she was going to stay off YouTube until tomorrow, but she has nobody to talk to, and nobody willing to validate her, except an audience of strangers on the internet, most of whom are there to watch her eat herself to death.
Poor Grandma. Do they have assisted dying for terminal patients in Canada? For somebody in a lot of pain, who knows they are ready to go, it can be a tremendous gift.
