I have lupus. It's not horrible, and the symptoms vary in intensity according to whether I'm having a flare or not. I'm on medication which keeps the flares to a minimum, which is nice.
But on the other hand, even with that medication, I never feel GOOD. Even on my best days, I'm tired and have some sort of low-grade muscle and joint pain. I've learned to live with it, for the most part.
What bothers me most, though, is the seeming inability to do the physical things I want to do. I love to dance, but I can only do it for about fifteen minutes at a time, tops. Then I begin to hurt, I get dizzy, I feel weak---basically everything just turns to yuck. I did fifteen minutes of Pilates earlier today, then later tried to do a "Walk Away the Pounds" DVD so I could get some kind of cardio workout.
Guys, I only got through about ten minutes of that thing before I just couldn't do any more. And now I'm feeling miserable both physically and emotionally. Even though I know I'm sick--it's been three years since my diagnosis--I still feel on some levels like I'm just lazy, and that I OUGHT to be able to do the same things as other people, at the same intensity.
I'm just so angry about this, and embarrassed, and guilty, and I guess I just needed to get it out there. Sorry for dumping on all of you, but I hate this stupid disease.

I'm so sorry! My brother was diagnosed with Lupus when he was 18, so I know (somewhat) what you are going through.
