I am sorry you are so sad. I have been where you are with three active boys to raise. It is so hard, but even though I didn't have an ounce of energy for me, they are what made me put one foot in front of the other to muddle through. No, I said I couldn't either, but for them, somehow I did. Your daughter needs you to be in this life for her. Sending you much love and lots of hugs.
