Gotta be careful who you complain to

Picard: I was part of a loving family with plenty of close friends while being a productive member of society working towards saving the planet...but it was futile so I consider that pretty traumatizing

O'Brien: I was a prisoner in a single room with a sand floor for 2 decades constantly on the brink of starvation and my only interaction with other sentient beings was a single other prisoner whom I mistakenly killed over moldy food

Well, at that point O'Brian still didn't have suffered through it.
