Decent physicians do the same:
“And the next time you feel your heart going out of rhythm, just hold your breath, and remember I will see you again a couple of weeks from now.”
Ah wait, no they don’t, because “resilience” is a worthless concept in emergencies, both mental and physical.
Decent physicians recommend exercise among other preventative measures to reduce the likelihood of emergencies.
Therapists will likewise encourage you to build up resilience so that "a relationship ended" is not a crisis, and also build support networks of real people who can really come visit you when you need urgent support.
There are also, of course, crisis hotlines.
The point is to try and limit what becomes an emergency in the first place. Having an argument with a spouse shouldn't necessitate an immediate call to a therapist.
