Telling someone their problems aren’t real and it’s just mental health is a textbook example of patronizing them.
Tell me you know nothing about mental health without telling me you know nothing about mental health.
Mental health problems are absolutely 100% real. It’s not “in your head”. Depression isn’t something you can just walk off. Panic attacks aren’t something you can fix by taking a sick day.
To imply that “mental health = not real” is not only destructive, but also incredibly insulting.
