my husband just starting working as I nurse this year and it expected to rotating work night shifts

i hate it, its weird its like I don't know when to go to bed as I don't want to go because he is not home but he is not coming home so I have to go,

I don't sleep properly get up in the mornings and if I am working I don't see him until I get home of an evening spend 2-3 hrs with him and then it starts all over again

Any ideas on what I should do when he works nights, no family or other real support
