If you really just gotta do something then why not just some GPP? Sleds, tires, sandbags, sledgehammer, body-weight circuits, hill sprints... the list goes on...
And it'll actually help you instead of grind you into the ground (assuming the intensity and length of cardio is appropriate).
I had a shitty day at work today and was completely wired and agitated as shit but I just did a full body workout yesterday so instead of hitting the gym again I went for a bike ride.
The cardio helps increase my ability to recover and more importantly my health... I'm not getting stronger if I'm dead from a heart attack lol.
