Ever want to just stop everything?

I keep a really busy schedule.
I am a full time college student.
I work 36 hours a week.
I’m part of a sports team that practices 2–3 hours a night
monday-friday
interval training on saturdays.
I run in addition to that almost every day
have homework, and try to maintain a little bit of a social life
so on and so forth
anyway

usually, I’m ok with managing these things,
as I’d rather stay busy most the time….
however, every once in awhile,
I just get tired, not neccessarilly sleepy tired
but – tired in the sense of
I just want to stop everything,
and I question
my rationale for doing all of these things
in the first place fairly heavily.

It usually passes in a couple days, sometimes it doesn’t.
Anybody else feel similarly?
