Lord help this person to nourish them self properly by eating the right food for them self, and by walking as much as possible. Heal them from whatever caused them to faint, plus take away all their anxieties by putting them all at you feet. May they go to the doctor to have their blood check to make sure their sugar, and salt intake are not too high, or that their is nothing else wrong with them. I pray in the powerful name of Jesus, amen.
Philippians 4:6
Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God.
