Hello brother; I'm sorry you are here (but glad that I know you'll get some great support). I do know the intense pain you must be going thru, and as trite as it sounds, it WILL get better, but you are in for a long hard battle here -- mentally, emotionally, legally, spiritually.
Put on the WHOLE ARMOR OF GOD, and strap yourself in. Life just dealt you a great bit chit sandwich, and how you respond to this will be a defining moment -- perhaps THE defining moment thus far -- in your life, and the lives of your daughters.
I'll have more later, but try reading one Psalm and one Proverbs chapter each morning -- it helps.
