Why not just say, "Mother Mary, I hand this situation over to you. Take over, please; and help!" Putting this in words will be very pleasing to Mary. She always loves to hear from you!
That's wonderful that you are consecrated to her and include her in your morning offerings!
I, too, am consecrated to our Lady and mention her in my morning offering, but I wouldn't hesitate to call upon her to take over when things became too hard for me. But because you are consecrated to Mary she is already operating in your life for sure. Just to clarify.
