How do you deal with letting go of things you can't control my son has RSV at the moment and I'm a serious control freak and it's so frustrating that I can't control this virus to make it go away....I'm seriously trying now but it's so hard when you hear people saying watch for this then oh no that's really bad and no he's fine then uh uh that's no good take him in I'm laying it in gods hands now.
