Am i a bad mom?

I am a first time mom and my baby is just 3 weeks old. I feel exhausted, clueless and lost sometimes. My baby cries alot, always want to be held and i get frustrated at myself for not able to console him. Everything seems to be so challenging and i am overwhelmed. My husband and i gets into arguments almost every other day due to the stress and tiredness from being new parents. There is no intimacy anymore. We only have each other because our family lives in another country. I feel lonely and alone on some days. We do not have any help and im also stress about my low supply of breastmilk. Waking up every 3 hours, and yield only less than 50ml each time makes me feel useless. Sometimes i cant even wake up every 3 hours because when baby sleeps, that is the only 1-2hours i can have naps. I feel bad not giving my baby much, 6 times out of 8 i will give him formula. I feel like a bad mom. #pleasehelp #advicepls #1stimemom #firstbaby #firstmom
