Exclusive pumping causing mental stress

Hi, i am just 12 days pp. initially i had decided to exclusive bf but my baby isn’t latching even after multiple efforts, so then i decided to do exclusive pumping. But i am not able to make time to pump 8 times a day, its taking a toll on me mentally and i am just not getting enough time with my bub. Is it okay if I switch to combo feed of formula and breast milk, i am not able to decide as it makes me feel guilty about switching to formula for a few feeds?
