A lot of things happened to her in the last 8 episodes or so....betrayals(some perceived, some real), spurned, counselors dying/murdered, a shock about the throne, "children" dying. It amazes me how many people have not understood what the Song of Ice and Fire is all about, how many think it's a fantasy fairy tale. Anyway, I wish we could sit down and have a beer and talk about it. I've changed a lot of minds about what happened and why, talking to people in person and in social media where everything is thrown out in the open. I'm already afraid I've dropped too many spoilers in a no spoiler thread.
One thing I'd bet on, this is exactly how Martin intended to end the series.
I leave you with this one quote:
"Fear it is"
