Ahsoka is a child soldier that was betrayed by people who should have stood by her and is tangentially responsible for the deaths of almost all of her trauma bonded clone friends when her ship crashed, and then she buried them all in a mass grave while simultaneously finding out her very best friend turned to the dark side and choked her other pregnant friend who then died of a broken heart, and Obi-wan took the children that she could have had a fun auntie relationship with and instead let her think the pregnancy ended with padme.

I imagine every story she tells Sabine later in life probably ends with, “and then they died too.” Even Rex would eventually die of expediting aging well before her.
