Your son has been playing computer games all day and all night. He forgot to eat because of the game that he's playing, and it has affected his school performance.

What should you do?
Your co-worker is unusually talkative and seems to be on edge. She sent an email to all the staff in your organisation regarding a personal matter which was somewhat incoherent.
What can you do with her situation?
