Complaining will get you nowhere. Its time to get up and do something about it. You should be thankful for the good things in life rather than focus on the negative.
There're 6 billion people here. We all have our own problems. And no, don't blame your problems on God. Everything that comes from Him is good, super-good rather. Its all a matter of perspective.
Take a fall as a lesson, get back up. If life was smooth sailing all the way, what kind of test is that anyway?
It is all a test of character. How strong are you? How strong is your faith?
Don't question why, for He works in very mysterious ways. The reason you didn't get a job today might be a better one awaits you tommorow. He always answers your prayers, in ways you would never have imagined, but He answers it all the same. For He loves you, and He knows what is best.
That is why he is God. Don't ask why. That's why it is called faith.
Find your peace, you mangkok.
