Depression/Lupus

I was diagnosed with Lupus in 2001 after about 8 years of running from doctor to doctor. The tests etc. that I had to endure caused a depression and since the diagnosis the depression has slowly gotten worse. The doctor keeps trying new drugs along with Wellbutrin XL but nothing seems to make a dent. I am already at the point where dealing with people is an effort. I’m tired of hearing “you’re not feeling well again” from well meaning friends and family. Just looking for anyone who has any suggestion what so ever or how to move forward from this. Depression can be treated, Lupus can only be treated by treating the symptoms and the flares, not the disease so it will be with me forever. The doctor recently asked me a question that I couldn’t happen, what came first the depression or the lupus. Did one bring about the other? I don’t know.
