I really hate myself sometimes. I was just in a lecture when the lecturer said we were going to have some sort of demonstration and that he'd randomly choose 3 out of the 40-ish people there to perform the demonstration in front of the others. I could feel the anxiety build up and then, after a few minutes, I panicked and left before the lecturer could chose "volunteers". I'm so anxious I'm shaking and I feel like crying. I'm now going to miss half of the lecture due to social anxiety. So disappointed in myself.
