Yeah, anxiety and depression are definitely part of the human condition. It's healthy to be anxious in certain situations and I don't know anybody who doesn't experience symptoms of depression at times. Not that they have an anxiety or depressive disorder that interferes with their day to day lives significantly,
but I think it's easier to understand for the lay person "I'm hopeless, sad, tired, numb, and don't really feel like doing anything or talking to people" or "I'm nervous/worried/scared/fearful and it's doing all these things to my body," than "when I'm off meds I go to other universes" or "eating makes me feel disgusting and guilty and I don't want to do it anymore" or "my girlfriend said she wants a little space today so that means she hates me, is going to leave me forever, and I want to kill myself" followed by self injurious or impulsive and reckless behaviors.
