ADHD Medication Helps My Focus, So Why Am I Still Exhausted?

My focus has improved with medication, but the overwhelming fatigue hasn’t changed. I’m not simply sleepy. It feels like my body and brain have completely run out of power. By the time I finish work, I have nothing left for chores, friends, or even replying to messages. My partner helps without complaining, but I still struggle with guilt. Most weekends are spent recovering just enough to do it all again. I’m tracking my sleep, medication timing, and energy crashes to discuss with my doctor because I know severe fatigue can have different causes. Has anyone else experienced this?
