I’m a night owl trying to get a job that I can keep but can’t seem to stay up during the day consistently.

I'm a night owl, but my household tries to get me to stay up in the mornings. For reference, I can stay awake as early as 11am, but can't get to sleep before 2am if I do. I'm afraid I won't be able to spend time with my family if I get a night shift, and they're always trying to sleep at night. Lately I've been getting 12 hours a day of sleep trying to force myself to get on a day schedule, but it never works out. Am I just unable to stay up during the mornings? Is there a way to fix it knowing I can't even force myself up via morning alarms? If so, how? If not, what do I do?
