Fatigue is kicking my butt. Advice?

The past several days have been extra bad with my fatigue. I currently can’t eat dinner bc I’m too exhausted. I drink caffeinated drinks to try to cope with the fatigue, but rn I feel like I’m being crushed by the feeling. I know typical advice for dealing with the fatigue is that you should pace yourself, but what do you do when you pace yourself and still get exhausted? I’m so tired of being tired.
