Life Update

Yesterday was a weird day for me. I already know this post won't be able to reflect how I'm feeling.
I had a doctor's appointment at 7:45am- insanity, I know, but I had to get in to see a doc asap.
So, I went to the doctor for something completely different, and she happened to see the blood work I had just had done to check my liver. My family doctor had recently assured me that my liver tests weren't that abnormal, and it was nothing to worry about. However, the doctor I was seeing happened to also specialize in livers. She saw my liver tests (kind of by accident) and was shocked that my family doctor had written it off. After taking the time to look over all my recent blood work she said it looked like I have auto immune hepatitis and scheduled a liver biopsy (two days before my birthday) to confirm her diagnosis, and to see what stage of liver failure I'm in. If a liver biopsy is anything like the kidney biopsy I had, I'm in for loads of fun. How blessed am I, though, that she saw that blood work? I could have gone years and never known, until it was too late.
The other bit of news I received was that I've finally tested positive for lupus. I kind of have mixed emotions. Finally I have a diagnosis, but at the same time I don't know that I wanted to know. If that makes sense.
So yesterday was weird. I'm having two minor surgeries in the next two weeks. I got two bits of life changing news, and I don't know how I feel. How am I supposed to feel? Maybe I'm being melodramatic.  Although, I don't know if I really care that much about my liver and my lupus.  I mean, it's like my health is a job. Taking care of everything is work, and how much worse could two more things be? Or maybe I do care. Or maybe I'm too overwhelmed to really absorb it right now.
I just wonder what my purpose is. What could it be, if all I am is sick? What does God want me to do? Am I just going to die in the next 20 years and that's it? What am I supposed to do.
