Darkness,
You have learned something important. You learned that you "can" move forward even when you are so stressed. You have a challenge with anticipation anxiety and you are slowly finding out that you "can" accomplish something even though you feel anxious about it. Just so you know, this is something a lot of first year college students struggle with until they slowly adjust to learning and figuring things out. You know what, some of the best and successful performers experience terrible stage fright and have to figure out how to work around that problem. That is very similar to what you have been describing.

You did well, you got a 79 even though you had so much worry. Good for you!! See how you feel now, more confident? That's what comes from making gains, you are learning and we only learn by doing. Each time you make progress you will gain something very important. This is how we slowly learn to thrive on our own.
