This author's idea that no one who's making fun of her has ever had any traumatic or difficult experience is laughable.
Most people with traumatic shit in their past learn that it's not great to let your emotional whims take over. They get CBT and other types of therapies designed to ensure that they don't make the lives of the people around them miserable with constantly being triggered. They learn the virtue of keeping their bullshit to themselves, because endlessly rehashing it doesn't actually help. They learn not to wrap themselves in cotton wool, and not to avoid life in hopes of avoiding triggers.
They also learn that huge numbers of people have tragic back stories and that having one doesn't make you unique or special. And that believing everyone who's handling life better than you had a charmed life is stupid and inaccurate.
If you're reading this, Sam Dylan Finch who googles herself, the people on this website have been bullied for their sexuality, appearance, etc.. Some have tried to commit suicide as teenagers. Some were abused. Some were neglected. Some have mental illnesses. The key difference between here and a place like EF: none of us thinks that gives us a free pass to behave in abusive or narcissistic ways to the people around us.
When you demand everything around you be constantly assessed for whether it could trigger you, and you make other people responsible for your emotions, you're engaging with the world in a narcissistic way. You claim you're a traumatized borderline but everything about you screams "covert narcissist" using other diagnoses as a shield.
