Welcome to WHL! I'm somewhat new to the site as well (only been a member for a few months) and it's been absolutley amazing. When I joined, I was still waiting for a dx. I got a dx last month, and it's so helpful to talk to people who are dealing with the same things.
I'm so sorry to hear your son has SLE, but I'm glad he's doing better and back in school. I went 10 years waiting for a diagnosis, 8 of which were during my remainding years of school. It's so glad to hear he has your community's support.
All I can say is, don't hesitate to ask ANYTHING! There's almost always someone on the site, and even if they don't have advice for your question, they always have their support. We can all relate here.
