Many of my biggest heroes have suffered from mental illness, particularly depression. I would like to place some of those artistic, academic and political geniuses in front of whoever made that comment and ask who is more "human", the ones who have actually contributed to the human experience at large despite highly debilitating illnesses, or the prejudiced jerk on the other side of a computer screen belittling the experiences of others.
You are a person. We all are. Don't let the bullies of the world tell you otherwise.
