The best thing to do about the feelings that bother you the most, is talk with God about them. God is always there, and he wants to help you. He already knows and he loves you. God is in control. If you believe that, you must learn to surrender to his will. This includes his timing and his plans. Peace and a calm mind are sure to follow.
“Cast all your care upon him; for he careth for you.” (1 Peter 5:7)
