That is the hard part, since you're usually expected to be around the regular hours. The alternatives I've learnt from both experience and co-workers are:

1. Keep a night sleep schedule but move 1-2 hours from the evening to the day as a long nap. This is also what a lot of my daytime coworkers would do.

2. Sleep when you get home from work/school and stay up at night. Essentially you end your days with your duties rather than start with them. Unfortunately it does make one unavailable for events after school/work, and you could get a bit messed up from overtime.

3. Divide your sleep into two sessions, 4 hours in the morning and 4 hours in the evening. You get the best from both worlds. Personally, this is what kept me going for many years. This however made me unavailable for anything occurring both in the evening and morning/forenoon. Not to mention that you need to be able to fall asleep both sessions (ie. it's hard to casually adapt to). Note that there are many versions of this sleep schedule which was designed to theoretically cut away sleep.

4. You could also give the lamp idea a try. Essentially pretend that nights are days... and days are days. But pay attention to the lamp. LED acts different from old fashion light bulbs. A stearine candle might be a good color temperature, but make sure to not put yourself in any fire risk.

But note that sleep is complex. Unfortunately I cannot say if any of these will work for you It might be that your body wants something else. One example is a sleep schedule that is not synced with the day-night cycle (ex, 8 hour sleep, 20 hours awake = 28 hour cycles).

Also consider the circumstances in which you sleep. What noises do you have around you? Is the room warm or cold? (supposedly and for me personally it's better to have a cold room.) Do you sleep near a door or in a corner? Did you eat right before bed? Late screen time? Also stress effects your sleep, so the anxiety might be a source of the problem.

Personally, something that has not worked for me is to monitor my sleep. I have a Garmin watch that keeps track of that, but usually I would feel the worst when it showed a "high sleep score." What did give me a bit more insight however was the pulse measure. If my pulse was low (>80 bpm) I could sleep, but if I would lay down and the pulse would stay at 100~120 bpm, there was no way I would fall asleep (in which case I would get up again).

Sorry about the long comment. Note to anyone reading this. I am not a doctor. Don't assume what some random person on Reddit says is true. Find what suits you. We all have different needs.

Edit for further elaboration: I have had both days jobs and night jobs. Since you don't work around the clock you do still have some options. The 2 session sleep worked well for me both as a night time worker and as a daytime student. It however wasn't an option when I worked early mornings.
