drawbacks

I've heard "If God gives you something, but you look at its down side and complain about that, He'll take it away from you." This has happened to me, BUT still leaves me with a puzzle. If God operates like that, there are other situations that I "complain about" but those He DOESN'T take away...

I made a mistake a while back, and because of that I'm dealing with the unwelcome consequences of that mistake. For wisdom on what to do now, since there's "drawbacks" to any thing I would try with it.
