It took me years to accept the fact that I an disabled. I refused to fill out the form for a handicap placard, although to the rest of family it was obvious that I needed it. Apparently, d'Nile isn't just in Egypt. So finally, I put aside my pride and got a handicap placard. I certainly wasn't fooling anyone by not having the placard, and I was over fooling myself. I could couldn't even make it from the sidewalk to the front of the building. Surprisingly enough, it wasn't the Mixed Connective Tissue Disease the made me need the placard; rather, it was my Asthma. Believe it or not Asthma can be very debilitating and disabling.
The other thing that makes me feel invisible is when you are a patient in the hospital when you hear the staff discussing you. Suddenly you become the one with the migraine, asthma, etc in room such and such. Suddenly your personhood has become interchangeable with a disease.
