I know how you feel. My plans for living have been broken twice, so far: once when my health got me out of conscription (while I was mentally prepared to go through the mental torture that is Russian Army, all the while the health "problem" is gone now and was just a minor fluke), another time when I didn't the five more points (out of hundred) of the History exam necessary to attend the Novosibirsk State Uni (which is located right near my favourite Russian city).
It sucks, but you'll soldier on. Life doesn't stop there, nor does your well-being. I worked a variety of jobs during the gap year, and it's been a good experience for me. I hope it's going to be so for you, whatever you decide to do. Have strength, and have faith.
