This is the chart, right ? Seems like your favorite quote goes quite well with the chart ("Life is like wrestling a gorilla, you don't stop when you get tired, you stop when the gorilla gets tired").
I would say the gorilla is that Mars in Capricorn in the 12th house, on the dark side of the Ascendant - a hidden enemy whose breath you always feel close in the back, although it doesn't necessarily has to be so.
Jupiter's transit in the last months in square Mars might have pushed you to overwork, to exaggerate, to give out more of yourself, and therefore to get tired.
Also, Saturn is very involved during this period in activating the natal Jupiter-Uranus square Neptune-Mercury (since last year) and bringing up many relationship issues as it travels through the 7th house and conjuncts the Descendant, but the good news is that the "reality's cold shower" will very likely end by midsummer, as Saturn steps into Leo on July 16.
