How can I have a good life and be so unhappy.

What are you talking about? "God will take away my life because I'm not using it"?
He hasn't taken away the lives of those who abuse others including children, or those who are the cause of violence and war.
Start a rethink - find something to with your life that will make you feel fulfilled, even in small ways. Try doing some volunteer work for a start.

Maybe having this realization is the beginning of you figuring out what you want to do with the next part of your life. Discontent usually fuels change so you might be exactly where you were meant to be right now.

Using your life in comparison to whom? Who are you trying to justify yourself to? Your life is YOUR life, and if you are happy then it is NOBODY's business but your own :)

It can't be good if you're unhappy. It won't be taken away, there's far worse people in the world. Find what makes you genuinely happy. You got this.

Eat more mints.
