3rd shift is killing my relationship.

I am a nurse, and I love my job. When I first started I worked 1st shift, but I actually really hated it and debated on quitting because of how stressful it was on me.. ( my boyfriend didn’t understand) I suffer with anxiety on a daily basis. So I thought I’d pick up different shifts to try them out, little did I know, I’d fall inlove with 3rd shift. I absolutely love working now but I can’t stand sleeping all day because of how exhausted I get when I get home. My boyfriend hates me always sleeping and tells me how he don’t understand how someone can sleep all day 9 + hours. I try to explain how the human body was developed to fall asleep during night, so adjusting to staying awake is difficult. I just wish he’d understand that I am trying. He’s in construction so he doesn’t work during winter. I don’t know how to handle this.
