Need help scheduling my workouts with a busy work schedule please help?

I'm a bodybuilder and I'm nearly exhausted everyday trying to work as a server at a restaurant with quick turnaround and an inconsistent schedule. The earliest I come in each day is 10am and the latest 12-2am leaving. I'm having trouble scheduling my workouts without being completely exhausted to lift and complete them. Any advice? When should I schedule my workouts with working an inconsistent schedule. I feel unmotivated and depressed now that I can't get in my workouts. I tried going in at 4am but I just feel extremely exhausted. Any help would be appreciated. I’m also trying to balance a relationship as well ontop of all this
