I have felt the stigma of mental illness quite a bit. In fact, not that I'm in denial or anything, but I VERY rarely use the term "mental illness" when discussing PTSD...I typically just say that I have "anxiety." (Since so many people suffer from anxiety, there seems to be less of a stigma.)
For example, a few years ago I had to go into the hospital (for just a day) because of panic attacks. When I called my boss to let him know that I wouldn't be in, I told him that I was having panic, but I would NEVER tell him about the PTSD. I think, for me, it has to do with the reason for the PTSD: rape. (Oh, and saying THAT word aloud took YEARS!!) When the average person thinks of a PTSD sufferer, they think of two things: combat vets and rape victims. Since I am not a vet, I fear that people will automatically assume the second possibility. Even though it is true, it places an even greater stigma on me.
...Now you have me really thinking...I even feel the stigma in the doctor's office. For example, I hate listing all the medications I take, especially if they are strong medications such as Risperdol or something. The other day I was waiting outside the door of the doctor I am currently seeing for PTSD, and random doctors/researchers/etc. were passing by. I felt soooo self-consious because this doctor I'm seeing is the hospital's PTSD doc/researcher, and I hated (even strangers) knowing that I have PTSD.
I don't really know what will erase the stigma of rape, mental illness, or PTSD. Sure, education sounds like a good answer, but I'm not so sure. As a high school teacher, we have to do a brief unit on suicide prevention each year. We show these lame videos and pass out cards for students to fill out if they or someone they know is thinking about hurting themselves. Well, each year the kids laugh at the videos and make paper airplanes out of the cards. And, just like the many homophobic comments/slurs I hear in the hallway, the kids start calling each other "scitzo" as a joke.
Sorry this was so long, but this was an interesting question.
