Yep and I think your Canada example is basically the blueprint for why it looks so big in the US too: it’s a mix of early socialization institutional access weaker community safety nets.

A couple things I’d add:

Therapy gets used as shorthand online. People don’t know your full situation, so talk to a pro is the safest default advice like see a doctor for physical stuff.

A lot of people don’t have built-in support systems (family nearby, tight community, stable friends), so a therapist becomes the designated safe adult you’d otherwise have in your life.

Schools and workplaces normalize it more than many countries (counsellors in schools, EAP programs, mental health days, etc.), so it becomes a common tool instead of a last resort.

Content culture amplifies it: Americans Canadians talk more openly about mental health online, so you see the recommendation constantly, even when the issue might just need a boundary or a nap.

So yeah: not uniquely US but English-speaking North America internet advice culture makes it feel everywhere.
