Welcome to the site and please let us know if there is any way we can help you with what you're going through right now. It's what we're ultimately all here for... support and caring and information sharing.
Please keep in mind that there are many MANY more people out there that never come to these boards to report how well they are doing, or how well their kids are doing because treatment helps so much that they are out there living full, productive, happy lives & don't have the time to come here!
Children are very resilient, and while lupus often hits them harder at first (especially with kidney issues it seems), this doesn't mean treatment won't help immensely and put it back into remission. It's very possible this will happen for you and your daughter.
Take care.... ((((hugs))))
