Hi Catzz, I like you had a long road before I was finally diagnosed. Unfortunately my family and most of my so called friends decided I was making it all up to get attention. My husband was the only one who actually saw what was going on. I also had a pretty good idea what was wrong with me, given the fact autoimmune diseases run in my family and that the student doctors all seemed to think lupus fit my situation only to be shot down by their supervising doctor(s) all because my ANA was negative. I actually had a single positive ANA test only after treatment began and that was very low positive. I also got my diagnosis 2 years ago when I was 28, though a few months later I turned 29. Treatment will help you feel better. You will have good days and bad days, and you will need to learn to listen to your body and what your limitations are. I was in my early teens when I met 4 of the criteria, but have never really been what most people consider healthy or normal.
I suggest you look at The Lupus Book by Dr Wallace. It might help you understand more.
Finally, WELCOME to our little support group that has for some become a substitute for family at times.
