Well I am quite a bit older than you.
My whole family has lupus. My father was diagnosed when I was 8, then me at 12, then my sister about 8 years ago. We've all given blood so that genetic testing could be done to hopefully help others. My dad is doing well for 65. I have been in remission for 10 years and my sister has been for 4. What helped me the most was a positive attitude. It may sound silly but it really did help. I never felt good until I stopped all the drugs I was on. My best advice to you is reduce stress, get plenty if sleep, and eat right. It's ironic that I started feeling better when I moved away from family (stress), and became a vegetarian (for ethical reasons). I hope you start feeling better soon.
