I honestly feel like Paige's real feelings at this stage isn't that her life is crazy but that she feels like she's going crazy and paranoid, but we know she isn't.

So for me it's like a central contradiction--her life has been stable, but she's got just as much or more legitimate reason than most to feel anxious and fearful because she's picking up on something not being what it seems.

I agree that it's what she can't see that's most threatening. She's being lied to constantly by her parents, the people she needs to be able to trust, and on a deep level she knows this. She knows all is not as it appears. And yeah, I agree, she does think she might be going crazy.
