It’s 2:15am and I’m crying

It’s 2:15am and my sobbing along side my 3 week old. My husband is asleep and only helps at night on the weekends. He told me before bed in a few hours to wake him up and he would take over. I did. He held my baby while I peed and made a bottle then handed him back. My baby is refusing to eat for me and I told him this. He said maybe he isn’t hungry then fell back asleep Is it wrong I despise my husband because he can sleep and I can’t? Is it wrong I’m mentally breaking due to lack of sleep? Is it wrong I can’t calm my baby down because I’m so stressed it is rubbing off on him?
