Mystery Diagnosis

I'm 23 and I have an undiagnosed autoimmune disorder. Going through this process to reach a diagnosis has been frustrating. Labs, doctor's appointments, and the all the anxious nailbiting while waiting for results is starting to take its toll on me. I'm afraid while my family and friends insist on constant prayer I can't help but worry about what the diagnosis may be. Lupus is a serious disease. There's no cure, controversial treatments, and depending on it's severity, limited mobility and chances to enjoy life. I'm 23 and I've just started living and I can't help but wonder what impact this diagnosis may have.
