Someone once said to me, "Do you maybe think this is just all in your head?," and this really bothered me because she just didn't get it. She was annoyed at me for expressing my very real emotions at the time and was basically telling me to quit feeling sorry for myself. You don't tell someone who might have a mental illness that "it's all in their head."
