FIB, I am glad that things are moving along for you. Not what you wanted, I know. It is hard to leave behind the life we thought we were going to have. It is heartbreaking to think about not being with our children all the time.
But, try as hard as you can to see a future with some peace and happiness in it one day. Be open to the possibility that that you will be ok as will your children.
You will never be the same as you once were. But, in many good ways you will have grown and changed. You will find peace and love again. And you deserve it.
