Husband not helping with newborn

My baby girl is 5 days old and we were sent home 24 hours after she was born. I’m obviously a first time momma and I just feel as if my husband isn’t helping. He wasn’t able to take any time off of work or his college classes (he graduates this semester) and I completely understand he’s busy but I really feel like I need help. His family has helped me a ton by grocery shopping for me and bringing us dinners at the door. But he hasn’t even changed 1 of her diapers or fed her. He hasn’t gotten up at all at night to soothe her and it’s just becoming overwhelming for me. And I don’t think he realizes how hard this is for me. She’s a preemie and for the past 2-3 days has been eating every 1-1.5 hours. I’m getting no sleep. Sometimes by the time I feed her, burp, change her and pump I’ll lay down and she’ll start crying ready for the next feeding. I have major depression disorder and I’m so worried about getting postpartum depression. I don’t wanna be a bad mom. Earlier I was so tired when she was eating I could even see, everything was just blurry and I could barely keep my eyes open. And I just keep crying because I feel like I’m not doing good enough and I just wish my husband could see that and help me with her. And earlier I guess she woke up and started getting fussy and I didn’t hear her because I was sleeping and I guess my husband was talking to me saying she was about to cry and I I guess I said she’s okay in my sleep and then she started screaming and I woke up and he goes I told you she was about to cry! And then huffed and turned the other direction. Please I just really need some encouragement I feel like I’m not good enough
