Have a look at the Sedona Method or Natual Brilliance. Both require you to "let go' and everytime you pick it up again you can choose to just let it go.
What if you could just for this moment let go of thinking about it? Consider that right now in this very moment it make no difference whether it changes or not. It simply is what it is, There is nothing you can do about it anyway so what if you could just for now let go of it? Let go and do whatever else needs doing or just simply enjoy a quiet cuppa while looking at the flowers in the garden.
Letting go and letting God is a moment to moment thing. Some things you do need to do if you want them done, like making the bed washing the dishes, other things take care of them selves like the birds that visit your garden and the flowers that bloom.
When you feel yourself stuck just ask yourself, 'for now, just for this moment could I just let it go and if not now when could I let it go and just let this thng take care of itself in its own time?
