Struggling to model faith when life gets hard

Got laid off last month and I've been pretty angry about it. My kids have asked why daddy seems sad all the time. Really hit me that they're watching how I handle adversity. Started praying with them again at night like we used to. I want them to see that faith means trusting God even when things don't make sense. Still working through my own anger but at least they'll see dad turning to the Lord instead of just complaining.
