Come to Me, all you who are weary and burdened, and I will give you rest. (Matthew 11:28)
Trust in the Lord with all your heart and lean not on you own understanding; in all your ways acknowledge Him, and He will make your paths straight. (Proverbs 3:5-0) I am praying with you.
You have not been praying wrong. Only God can change hearts, and He will.
