Please, please just let me sleep

Holy crap, I'm exhausted. I can't tell you how many times in the middle of the night I've thought about giving up breastfeeding for a nap. During the day Nora eats like any  normal baby and I start to think "maybe she's leveling out" but then the sun goes down and she starts clusterfeeding. For hours. But! it never amounts to a long stretch of sleep. She'll eat for an hour and a half, going from one breast to the other, but then refuses to sleep for the  next hour, just fussing and wiggling and it's almost too much. Then! Then! She gets hungry in an hour and that's the whole night. Six in the morning rolls around and she finally (thankfully) falls asleep for an hour and a half. (She never goes three hours without a feeding. Two hours is our reprieve.)

I'm at the end of my rope and I swear I don't remember going through this before. Sure, I fed all day long, never leaving the couch when Mazzy was little, but she slept four to five hours at night and I was totally okay with the trade off. Having an normal infant makes me feel pulled and stretched and I kind of hate it. More than that I feel like I'm unprepared. I don't feel confident at all.

Everything tells me that things will calm down and she'll stretch out her feedings, but I'm not sure that I believe them.
