Lately my morning jogs feel exhausting instead of energizing—what changed?

I used to look forward to my early morning runs as a way to clear my head and start the day fresh. For the past few months, though, I’ve noticed that even a short 20-minute jog leaves me feeling wiped out and kind of anxious instead of refreshed. I haven’t changed my route much, but I did switch from running alone to running with a podcast - maybe that’s distracting me more than I realize? I’m also juggling a heavier work schedule lately, so maybe stress is playing a part. I’ve tried adjusting my sleep times and stretching more before heading out, but the tiredness sticks around no matter what. I want to get back to enjoying those runs without feeling drained or on edge afterward. Has anyone else experienced a sudden shift like this with something that used to be relaxing? Could running with a podcast actually be adding to my fatigue? What small changes helped you regain that energizing feeling from your workouts?
