1 weeks and 5 day old

She won't sleep at night. I have her on a schedule and she just keep getting crying 😢 like wtf. I am so tired, I am losing weight, my eyes look puffy. I'm about to lose my shit. I have a two year old as well and he's already busy!!!! My husband is gone for a month at work! I'm here by myself with postpartum, not sleeping, not eating, getting frustrated, getting irritated. I just want to be normal again, I want to be me again. I want to sleep normal, eat normal, think normal. Wtf can I do. She just won't stop crying at night. It's like soon as I get in a deep sleep she gets up crying. It's always 1200-100am 330-400am, and 600am it feels like she always wakes up at those times. I am about to lose myself and my shit. Help!
