I do think people forget that when Rhaenyra walked the castle battlements of Duskendale weeping, refusing to eat or sleep, she was, in all the ways, heartbreakingly alone. She was a mother with five children lost, a widow too (for some reason people forget this aspect?), a dragonrider who had her dragon with whom she had shared her cradle killed (the canon literally tells us that Syrax's death left her inconsolable). It's just very interesting how for some people everyone else is allowed to suffer and their losses are blown out of proportion, but Rhaenyra isn't, and her total losses (which were devastating) are of little to no value to some.
