What Could Cause Low Energy, Laziness, And Lack Of Motivation Despite Being Emotionally Okay, With Coffee Worsening Headaches?

Why am I lazy and have very low energy? I drink coffee sometimes but it’s making it worse (I get headaches) after a few hours. I’m very unmotivated in general, I find it hard to do basic hygiene stuff and I’m not sad, I’m ok emotionally most of the times
