No patience for my own child

Anyone else out there feeling like they have zero patience for their own kid?! All I see is lovey Dovey posts on here about babies and that's cool but don't parents have real life meltdowns?! Difficult times?? Difficult high needs babies?! If you do, please please share how your overcome them!!

I have two kids, one is 6 and one is 9 months and BOTH were and are high needs/ HORRIBLE sleepers as babies. My 9 month old naps twice a day for 10 min each, cranky throughout the entire day, always wanting to be entertained or held in my arms, bedtime around 8-9pm, wakes up about 10 times within an hour (no exaggeration there )before she falls asleep for the night but then is up every two hours to breastfeed. I absolutely cannot get a single thing done or even get a 5 minute break, not to mention get some honest sleep at night. I'm beginning to think I was never meant to be a mom!!!! And to add to my rage and fury, we live in a semi busy area in town, on the first floor so we here EVERYTHING, plus we have a stupid dog that barks his head off every time that front door in the building is opened !
