sad and empty

tonight I'm laying in bed crying myself to sleep while my 10 day old cries with a tummy ache in the next room with my mother. I just want to help, I want to soothe my baby. But nothing I do helps, I can't fix my baby's pain and it breaks my heart. I just want to be able to stay as calm as she does, to soothe him like her. But I'm exhausted, sad, and broken. so I just lay here.... waiting for feeding time again. I know this gets better, but I'm not sure I was built for this. I feel like a bad mother that I can't help my baby, that I need my own mother to help me so much.
