Lukewarm take: we need to stop using mental health/therapy buzzwords in day to day life. Not everyone you dislike is a narcissist. Being sad doesn’t mean you’re depressed. There’s a resounding difference between being nervous and having anxiety. You’re not ADHD because you don’t like to sit still. You’re not autistic because you’re quirky. OCD doesn’t mean you’re organized. And for the love of all that is holy, not every situation that made you uncomfortable is “trauma”.
i think one of the healthiest things i've ever learned is that you should allow others to reintroduce themselves to you, even your closest friends. Give people space to become who they are without assuming you know who they are just because you've been friends/family for years.
