When you have done all you can in your circumstances--give it up to God. This is so hard because we want to take control, but laying your prayers down will give you a sense of release and that God is the author of your story. Speak the Word of God over your life out loud. “Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ” (2 Corinthians 10:5). The scripture in Philippians 4:19 has also helped me. I would speak this frequently over my life and throughout my day such as:
"This world doesn’t dictate whether my needs are met. They are met according to the riches and glory by Christ Jesus (paraphrased). I don’t care what my bank account says and I don’t care what the economists say “Greater is He in me than he that is in the world” (1 John 4:4).
My God is greater than these circumstances!
