I asked my mom if motherhood is really that miserable

I'm cooooonstantly seeing and hearing mothers I know complain about how their kid is driving them crazy 
Or how they cannot wait to get away from them. Or how tired they are and how bad they want to be alone and want their kid to let them sleep. I see things shared on Facebook basically to "that mom" who is miserable. "You are enough, you are important, you are worthy" like I wondered is this what it's really like? Will I really need a reminder than I am worthy and enough? Honestly, that's some birth control right there.  So I asked my mom. Mother of 6 kids.
