I am sorry to read of your friends illness and I hope the Drs will soon have an answer to the cause of her symptoms.
Your friend is very lucky to have you in her life and I am sure you are lucky to have her - what are best friends for if not to care and yes, worry about each other when one is sick. The best thing you can do is just be there for her and not let yourself become ill from stressing out about what is going on.
Gentle Hugs to You,
