Well, you are doing nothing crazy.
My inclination is you are doing too much volume.
Drop down to this and see how you feel:
Cardio as desired but not everyday and not too exhausting.
Legs & back:
Leg xtensions
One type of squat or leg press
Leg curls
One back pulling exercise
One rowing exercise
Standing calf raise
Rest day
Chest & Shoulders:
Low incline bench press
Dips or cable low fly
One overhead pressing exercise
Rear delt laterals
Seated calf raise
Rest day
Repeat sequence
So example:
Sun-Tues-Thurs-Sat-Mon-Wed-Friday-Sun-etc or M-W-F and weekend off.
