Sorry for a lame question but what does “sectioned” mean in the context of this story?

Being sectioned means being admitted to hospital whether or not you agree to it. The legal authority for your admission to hospital comes from the Mental Health Act rather than from your consent. This is usually because you are unable or unwilling to consent.

I had to check also.

Basically means you are admitted to a secure unit of a hospital psychiatric reasons. You have no choice but to go there and will not be released until your deemed well by doctors.
