Is it stress or sleep?

The cars hurried off to the people's hospital despite Chi Lian's insistence through out the entire ride that she was doing okay. The old madam was worried about whatever it was that the doctors had seen on the scan of Chi Lian's brain. 

The old madam was also answering phone calls from her husband, the in-laws and Muyang himself. 

Chi Lian was truly fine physically, all the exhaustion she was feeling was just making her drowsy and she craved sleep. If she could just shut her eyes and fall on a bed for a few hours she would be fine. Listening to the old madam recount the tale of what happened in the MRI worried her a bit. Was her brain damaged?

"T4, was something detected in the scan of my brain?"
