"Do not be anxious about anything but in everything, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and minds in Christ Jesus. " Philipians 4:6-7
You are on the right track in just completely trusting the Lord...like Peter said in John 7:68-69, "Lord, to whom shall we go? You have the words of eternal life. We believe and know that you are the Holy One of God." We can stop trusting the Lord...walk away....but to whom will we go from there? There is no one else who gives us what God can give us...peace, direction, discernment, wisdom.
