Cares are anxieties. Cast your care on God by giving over the control of the situation to God, let him manage the flow of circumstances, give him the right to manage your feelings and let it go by faith.
Pray after you do something, not just before you do it. Thank God for giving you the desired result. After is when you’re most vulnerable to Satan. Trust in God that He hasn’t forgotten you, because He always shows up when you need Him.
