Hi Miranda, and welcome to WHL. I'm not the one to get advice from, other than I can tell to NOT do as I did. I didn't take care of myself and ignored symptoms for years. You pay for that in the long run. Definitely take care of yourself. You'll have to "feel around" a bit, get your meds & lupus "balanced", and go from there as to how much activity (and what type) you can deal with. That's impressive that you've gotten a Girl Scouts Gold Award. Not many young women can say that. Be sure and browse around the site.
