Hey, this happens to me a lot of time. Just for example, I spend a hour to write a post but don't get a good response. Thinking back, I sat for a couple of entrance exams for my higher studies but couldn't crack the one I desperately wanted.

Life doesn't always give you what you want. Nobody gets everything. There are times in everyone's life when all their hard and struggle and efforts go in vain and that too, because of something they didn't even do.

But that's life. You have your share of good and bad times. In such times, think about the other great things you have, your achievements, good memories and that's what helps you get out of the depression.
