Don't pray about whether you should or shouldn't, just follow God . God is not so small that you have to do something immoral to support your family. God will provide. Throughout the day, remember that Jesus is smiling at you. This will put a smile on you face or a smile in you soul.
All big things are a bunch of little things.
If you will not make a stand for Christ, at least don't get in the way of others who will make a stand. The giant Goliath was mocking the army of God. Eventually, he could look at them and they would turn away in shame. Make sure the devil doesn't have any power over you to shame you. Confess all sins and stand tall in the name of the living God.
