I have both, my vision is at times worse then normal, it will blur and not want to focus?? I have always had arthritis, I have wore glasses sence age7 I am now 50, and the dry eye problems have just been off and on worse over the last few years? I am extreamly fatigued, I have at times felt narcaleptic. I was startled when I heard a relative say, Hey! are you OK...I had nodded, with no warning. At times my own body feels like it is a chore to move, to lift my arms and I think I have my foot high enough to step over a object and No, opps! its embaressing! I perfer to be on the go, my daughter says I am like a hummingbird, for the way I flit around doing things, I was multi tasking before they gave it a lable! Well Imagin a Hummingbird with RA. and yes I battle with depression.Mostly for that reason, I hate not beeing able to get things done and move at the pace I want without tripping over my own feet!
