I'm not completely sure, but you may be refering to Syncope, a medical term which describes events such as fainting or passing out which occurs upon low blood flow to the brain. As a result it can occur when under shock or truama or a post-effect of stress.

Obviously, one would expect the opposite to happen in half the events, such as after vomiting, however when you said

have some major upheaval in their life, or experience some other trauma (eg. a bad breakup, losing a job, etc.). When the mind can't cope it simply shuts off and they fall asleep or pass out.

I realised you may be relating to someone feeling a depressed, in which case lowering of blood pressure is possible and thus he or she could suffer from syncope.

In all honesty it is simply a technical term for fainting, and is more commonly used for people who suffer a disorder which will cause them to faint often.

By the way, googling it works too.

Hope this helped, Mona.
