Just finished FB Insane Cardio Workout

So I just finished this grueling workout. Although it is a great workout, I don’t think I will do it again because it is so hard and the fact that the same groups keep repeating and they get longer and harder makes this workout almost mentally impossible for me. I tried to push myself, but it was so hard and part of me feels like I failed to push hard enough :( . I almost gave up, but I pushed to the end. I don’t feel so accomplished because I feel like I didn’t maybe I didn’t give my all, I kept feeling like giving up and think of when it would end:(.
