Your sensation of “energy” from having slept well or drinking coffee isn’t actually related to the concept of “energy” in physics. Feeling less tired can’t be converted directly into a driving force for chemical reactions that form unfavorable chemical bonds. You can’t turn gasoline, oxygen, and a tired person into carbon dioxide, water vapor, and a non-tired person.
Energy in physics can’t be created or destroyed, so you can have great fun tracking where it came from and where it went. The sensation you call “energy” can be created and destroyed, so it doesn’t have to have come from anywhere.
