Counterpoints to the OPs sig: Leia was also never enslaved, never taken away and forced to be detached, never actively looked down on by associates, never had someone close to her hunted down or turned on by said associates on a dime either.
All true, and yet, she still sacrificed everything for the Alliance and then the Resistance. In Episode IV, Leia is a 19-year-old Senator that has the plans to destroy the Death Star and proceeds to stand up and lie to Darth Vader in person. And of course, as already noted, her (adopted) home planet was destroyed in front of her own eyes.
