I commiserate! I know the feeling and the experience and I have seen it played out, many times. Not in Brazil, but other places in the world. And you're right, even the people who see it happen, know it's the rule rather than the exception, think that it won't be them, or is not them... until it is,

But it is still hopeful and people need to dream and try things, even with the risks, nor the world never changes.

I will say this though. Those who dreamt, risked, tried and experienced, are changed. They usually go back better for it and end up doing something more than the "quiet desperation", that so many of us end up in, rolling through day-after-day letting life lead. So be optimistic, thankful from the experience (however bad it seems now), and be open to risking and daring in the future (just with more lessons and maturity under your belt).
