I just found out my 13 year old cousin is taking prescription zoloft. He went to see a doctor because he couldn't pay attention in class and he can't remember things. His mind drifts away very easy, he plays minecraft and roblox all day and he has a notebook full of fucking sonic the hedgehog drawings. He used to play club penguin when he was younger. The thing is, he used to be very smart a few years ago, but now he is unable to recall things that he has memorised 5 minutes ago, he always keeps his head down and mumbles when asked questions.

It really breaks my heart. Can he be rescued? I'll talk my aunt and uncle into throwing his laptop away, but what else can be done?
