Gillian was seriously injured in the head and was taken to the hospital. What happened?

Gillian was seriously injured in the head and was taken to the hospital. It's about Gillian's dizziness when she went to the toilet in the morning, and then she accidentally hit her head on the counter in the bathroom, which happened to have prominent edges and corners, and then she was seriously injured and was taken to the hospital.

It should be due to the lack of mental energy caused by recent fatigue that people are more tired. Then after filling it up, the blood gas is not strong, which is easy to lead to unstable walking and dizziness, and accidentally hit it.
