Medication like Zoloft helped a ton for me with these things
"you may want to see a doctor, sometimes these things need medicated" seems like reasonable, responsible advice. But handing out specific drug recommendations - WTF?!
I experienced the same thing when my American cousins were over last summer. Unsolicited and highly dangerous medical advice tossed out like a TV show recommendation.
EDIT: I realise I do not actually know the nationality of the previous poster, and that their statement referred solely to themselves, yet I still feel it is dangerous and will leave the original message intact.
From branded medications to diet books, "health" foods, and trends ad nauseam, there's a pervasive culture of cure-all objects and systems.
Then again, we don't have fine physical understanding of most mind disorders or the medications we use to treat them so if your doctor is effectively throwing darts at a board then why not internet strangers?
Everyone in this thread trying to say general ignorance is something Americans have a monopoly on is silly. It's a human condition, nothing to do with country.
Many wealthy European countries have a much more suspicious attitude to health vendors. Then again we often ban their advertisements.
This is important, and why it is ok to say it IMO, and I'm glad GP did. It's an honest and real response.
I have a huge problem with the way some of these drugs are over-prescribed. But I have an even bigger problem with stigmatizing people who are availing themselves of a resource that might be of help to them.
Also I don't see why being a Brit would make a difference, I'm an Australian and hearing that a drug helped someone isn't that mindblowing to me.
On top of that, he'd have to convince a doctor to actually obtain the drug.
It just isn't the culture here to talk about specific medications. People are more likely to focus on the condition, and urge someone to go get checked out (often to 'demand a consultant' but I've never seen somebody explicitly or implicitly told to request a specific drug).
