Someday I feel lousy as a working mother. Is this normal? What may I do to feel better?

it's normal! i feel that way too! sometimes i feel like I'm failing in all areas coz I'm neither 100% there for work nor 100% there for my baby. but remember to be kind to yourself. motherhood is tough. i bet even SAHMs sometimes feel inadequate. try to take some breaks and do something that u enjoy. sometimes we just need to have some time to ourselves that's neither with work nor kids.
