My husband has just been diagnosed..help!

My husband has just been diagnosed with Lupus. I am very worried and it all seems to be a very serious complicated condition. I am very scared of what treatment he is having as he says it all just seems like big words. He has quite severe kidney involvement and is awaiting results of a biopsy. He has already had 3 IV bags of steriods which havn't seemed to have much effect on reducing something in his blood which was 80, then went to 160 and then to 200 (I'm not sure what this is) but it was indicating that inflammation in his kidneys was very high. He is now undergoing Chemotherapy. I'm so worried can anyone talk to me about this, has anyone been through the same symptoms? He has headaches, muscle aches, fatigue and slight nausea.
