Looks like one of the updates since I last played broke the game for me, my energy bar appears to be totally empty and all screens show "low energy" (even tasks that don't cost energy have that text & their buttons are disabled, so I can't gather berries or fish to get my energy back up)
maybe make it so tasks that don't cost energy don't check your energy meter? maybe my energy on my save went less than 0 somehow, idk
