SO working nights baby #1

I feel like I really need some advice, I'm currently 17weeks pregnant with our first child and my SO works nights and has done for a long time. I'm worried when the baby is here I won't be able to cope day and night alone. I used to suffer really bad depression and anxiety and my midwife said there's a high chance they can come back while I'm pregnant or just after the baby arrives due to all the changes going on. I need advice from moms who have been or are going through the same thing, my SO is currently looking at going onto days because I'll have family support in the day if he's not here where as a night I'll be alone with no one to turn to. But he really doesn't want to do it and keeps saying to me "well other people can do it so you can" it's really pissing me off, I feel like I've got no where to turn if I confide in him he billitles everything I say and just brushes it off. I think he thinks it's going to be really easy and the baby will sleep all day and night but I'm really stressing it's taken 4 years to conceive this baby as I had fertility problems but now I'm almost regretting it 😔😔 please help
