If there's anything I've learnt, things ALWAYS happen for a reason. Especially the "bad" things. On hindsight, they have always turned out for the better.
Of course, these situations are never easy. But you will always make it out of there, in a much better place.
Cry/ moan/ whine for a while. Letting out those extra emotions are always healthy. Once its over suck it all up and turn all that into POSITIVE energy!
What's that but a little obstacle. Think of all the people who are much less fortunate, who have no aim in their lives but only to survive long enough to see the next sunrise.
And then realize that life has been kind to you.
Then find that determination to overcome the obstacle ahead.
Success will only be found by those who seek it. Those who wait to be found by success will be waiting forever.
