Deteriorating health and dull skin after weekly rotational shifts. Need tips to survive!(M23)

It's my first job(tech, joined 3 months ago) and I can't make a switch now. Im at my lowest, and my energy is getting low day after day. I'll have a week of night shift every month, remaining morning and noon shifts(manageable).

But this night shifts, I really can't do it. Thinking about it is giving me anxiety now. It'll take a week to get back to normal sleeping schedule, and the moment it's getting consistent, another night shift😭. I was hitting the gym, moving my body, and my glowing face is no longer here. People recently started asking me what happened to me🥲. Im getting darker and dull. After a night shift, i skip both breakfast and lunch, dont even feel to wake my body up. Oh and top of that, my project is kinda toxic. Pressure is there. But manageable. I thought of resigning, but remembered my unemployment days.

So folks who has even complicated shift timings, how do y'all manage?
