I agree with the self-worthlessness part. Much of that was already present in the novelization from what I can tell. I tried to hone in on it even more.

But the idea that Rey believes she is doomed is a completely different idea. You are suggesting that Rey is nihilistic.

If she is, then the question becomes this: why does she accept the lightsaber back from Leia before she heads out? And why does she feel like she can prevent Palpatine from taking over in the first place? It’s because she doesn’t want to believe the visions yet. Sure, they’re making her doubt herself and making her feel unworthy, but she hasn’t considered it as an inevitability.

Only when she travels to Ahch-To would I describe her as nihilistic. But of course, Luke points her in the right direction in that dark moment.

I also feel that Faraday is right. These sort of things are going to be different for everybody.
