Depressed

So my husband and I had a argument tonight I have 4 kids under 4 and he works nights 6pm to 6am 5 days a week. Not only that the job is about a hour and a half away so he leaves about 3pm and doesn’t get home until about 8am and I’m tired of it I’m tired of being alone all day and night and getting no help with the kids be he is gone all night and sleeps all day. I even asked him to at least go to days so He is somewhat on the same schedule as everyone in the house and he won’t do it. He gets 2 days off which doesn’t help because he is still on the same schedule I’m beginning to become depressed what should I do?
