Wow, reading some of these (especially the "cream pie" remark, and the cerebral palsy remark), I think the things that people have said to me barely even rate!
The remarks that stuck with me are the ones that implied I was not actually mentally ill at all, but merely seeking attention or feeling sorry for myself. My mom used to always say I was just "being overly dramatic", but she came around after about a decade. Two men, both of whom were interested in me, said something along the lines of "there's nothing wrong with you, you just need to get laid". (No self-interest there, I'm sure, lol) One friend said something like "I dont know much about mental illness, and I'm trying to understand it better, but it seems to me that you are just looking for attention". I almost ceased my friendship with her right then and there. But, over time, I realized that despite her lack of understanding, she always stuck by me. She phones once a month or so, even though I make no effort to contact her. There were many people who said the "right" thing to my face, and either trashed me behind my back, or ghosted me, so I chose to just accept this particular person's limitations and move on. However, all the other people who said snotty or disingenuous things (including the "life coach" who had me watch a Tony Robbins vidéo in which he describes depression as "selfish") have been cut from my life. I know a lot of people don't understand, but I'm not taking the time to personally educate every single one of them.
