Am I a bad mom

I had a difficult pregnancy and my child's father in the 4th month of pregnancy went awol and said he was depressed. I went through with delivering my little girl with my younger brother's girlfriend after being alone in labour of 12 hours.

Im a single mom. zero support from the dad, I feel like a bad mom sometimes cause I sometimes get frustrated when my child cries uncontrollably and I cant calm her down, the other day I screamed at her, felt so guilty the next day cause I feel as though I might hurt her.
