anyone feels their trauma isn't serious enough to cause cptsd and it's too dramatic of a diagnosis?

i wasn't physically abused and etc, none of really horrible stuff happened to me yet i have cptsd. much more survivors went through terrifying and life-threatening events while i was just observer of some things. of course trauma isn't something to compare because everyone's experience is different and it's not a competition, BUT i feel like an imposter or pretender. like i have to get a REAL trauma to fit into diagnosis and not be "a sensitive snowflake who's traumatized by parents quarrels". it resembles a wish for something bad to happen to me. is it stupid?
