Hi Sarah,
Reading your post reminds me of the lives of so many of the Saints.......none that I have read about had an easy life...St. Padre Pio, St. Therese, John of the Cross, St Rita, Little Margaret of Umbrio....so many had one tough time. If you can find a book on the lives of the Saints reading it will give you inspiration and courage in your life.
I will be remembering you in my prayers and ask for your prayers also...God bless you.
