My own theory on this is something like the following :

Weiss's father is a king, and it's a paterneal lineage. But the king has only ever had a daughter, or else her older brother didn't pass the required test to qualify as Prince. I think the armor is an ancient test to test for the fitness of the royal heir.

So the 'Royal Test' that Weiss is troubled by is the golem. And it's possible that test cost her her big brother. Either way, the test left it's scars on her, and she is forever not 'measuring up' because she's a girl, not a male. This would give ample reason to be cold and yearning, plus burdened by a Royal Test.
