I wake up and I say, "God this "problem/issue/person" is yours. I can't handle it but it's all yours."
I have memorized scripture to help me with this... Here are a few of my favorite scriptures:
-Psalms 56:6 When I am afraid I will trust in you.
-2 Timothy 1:7 For God has not given you a spirit of fear but of power and of love and of a sound mind.
