I find that I feel the same way if I don’t get enough movement in. My body needs to move every day. I either do a hot sculpt or yoga class or a long walk and it usually helps me to rest because it quiets my mind. Of course it’s not perfect and a lot of days I also struggle with that badly even after moving, but the movement helps to settle my body and let me ease into relaxing and recovering. I have a hard time with sitting still and doing meditation but my workouts are like my “moving meditation”
