Have you tried changing your diet? Keto, Mediterranean, Vegan. I've known people who have all benefited by finding a diet that works for them. I personally never eat past 6:30 or before 6:30 the next morning and eat keto and my energy has rebounded a lot in the past few months. Regular sleep schedule also helps, I'm always in bed by midnight unless it's an emergency (a real one) of some sort.
