What to do when you can’t get a Dua out of your mind?

I am currently waiting for my US visa to join my husband there. It’s one of the major duas in my life. There is currently a pause going on and I feel bad and pray for each one of us even people before me in the line. I have started praying a lot more regularly. I remember God often. All the time actually. I cry on little things and everything. Even though I have enough evidence from my own life that He does the best at the best Times I still feel so helpless lately. What can I do? Help a sister
