You'll be okay. I still get nerve pain if I feel stressed out, but I just remind myself that it's there because of stress. Usually deep breathing and just knowing that it's very temporary will make it go away in a day. You're very young. Aim to stop the loop of worried thinking now, at your age. You are fortunate to have found Sarno while in your early 20's. You have spared yourself a lot of pain. Be happy. Let yourself be young and enjoy your life. Look for ways to take your mind off of your body sensations. You got this.
