Prayer to relieve stress in relationship

I need prayer that I be relieved of physical and mental stress of worry. I am in a relationship that we feel God has placed us together, but due to a previous marriage and children involved, stress prevails.

We want to glorify God in all we do and believe that He has brought us together. We want the best for our children as a blended family. We pray that stress will be relieved as we follow God’s plan for our lives.
