She will when Steven goes to Homeworld to talk to the Diamonds, in the hopes of getting advice on how to be a better Diamond and how to deal with his feelings of inadequacy and alienation.
But they can't help him, because until he came along they were basically doing just fine - and now that everything is different they are still fine. They are free. They can do whatever they want.
Yellow does nothing at all.
Blue has begun planting a garden.
And White is travelling from planet to planet to assess, one by one, what she has been missing.
They just don't get what is wrong.
And then he encounters Spinel, who hangs around the Diamonds, and she seems oddly wistful that he is sad and defeated. So they talk, and for a little while he feels better because she understands Pink Diamond better than anyone, because she was made in her image.
But her final remark makes clear she doesn't understand it at all - that there really is no-one to connect with, that he is all alone... and he realizes that this is how his mother felt: all alone.
That is when he really loses it and turns into Gemzilla.
Honestly, it's just another Pink tantrum, only exacerbated by the fact he is also a teenage boy, and if teenage boys are good at anything it's thinking nobody understands them.
