Faith is moving forward one step at a time. Do the next thing. I've been there many times, and it always works. Do the next thing, and trust that God is good all the time, even though life is not. It always gets better.
Sometimes God keeps us awake, or randomly wakes us up at night to pray for friends, enemies, anyone or anything. He even gives us spiritual dreams to tell us what we're supposed to pray for, that's awesome.
