Daniel Wiffen is sick

My friend Daniel Wiffen is sick. He has been sick for a long time. I don't know what he has, but I know that he is in a lot of pain. He has been to the doctor many times, but the doctors can't figure out what's wrong with him.
Daniel is a really great guy. He's always been there for me, and he's always made me laugh. I don't know what I would do without him.
I'm really worried about Daniel. I don't know what's going to happen to him. I just hope that he gets better soon.
Update: Daniel has been diagnosed with a rare form of cancer. He is currently undergoing treatment, and the doctors are hopeful that he will make a full recovery.
