Many years ago I faced discrimination for being on government healthcare (Medicaid). That was not about a mental health condition, I had gone to the ER for a kidney infection. A cranky old nurse sneered at me and made some nasty remark to another nurse about me being on Medicaid. Back then I was ashamed (I was 25 years old). Today? Ha! I'm 30 years older. I would call her out on it, get her stinking name, and report her ASAP. She would be ashamed for the day she was born.
So far the only obvious discrimination regarding mental illness I have faced is, unfortunately, from my own daughter. I truly believe that she means well, but it annoys me when she tells me I need to speak with my pdoc because I am "having symptoms". Usually this happens when I disagree with her
