It was funny, she sent me a 4-page devotional on Tuesday about that very thing - that it can be sinful to worry and not allow God to work things in His way without fretting, that worrying is actually refusing to put your faith and trust in His wisdom.
Prayers sent up for you and your family Proverbs 3:5-6
Pr 3:5 Trust in the LORD with all thine heart; and lean not unto thine own understanding.
6 In all thy ways acknowledge him, and he shall direct thy paths.
