I graduated BS in Psychology, and then Masters with Emphasis in HR Management. Right there with you. I walked the stage both times. Both times my anxiety was so high, but both times the moment was so short. You are a blink of an eye, and you need to take part in the accomplishment. You will be fine . I rehearsed the the graduation process 100 times in my mind each time before the stage walk, but got through it. Good luck, and congrats!
