EBF starting to feel overwhelming

So with my first she never latched so I only pumped, I thought I was thankful that my second latched successfully but I’m kinda starting to feel trapped. She nurses everyone 2hrs without fail for about 15 minutes. And honestly I feel like my whole life revolves around the nursing schedule. It’s difficult to get errands done because by the time I get everything ready to go and get my 3 year old in the car by the time we get to the store it’s time to nurse again. I’ve nursed in the car and made my 3yo wait but understandably she gets anxious and has a hard time waiting while I fed her sister.

I just getting a little overwhelmed with how demanding exclusively nursing is. I’m worried that if I rotate a few bottle feedings I’ll feel more overwhelmed because I’ll have to pump and then bottle fed. I’m doing my best to avoid formula as long as possible.

Anyone else feel this way? Any suggestions for a better schedule? Every 2hrs she’s fussing to be fed, she’s 5 weeks tomorrow
