shadow11 I don't know if this will help you, but my friend use to say "worrying is making oneself suffer before anything even happens". Living in the "what if's" is mentally exhaustive and I tend to imagine things to be way worse than the actual outcome. Saying "Stop" in my mind helps break the negative cycle. Perhaps try to practice positive visualization and imagine yourself walking into class, being successful, meeting great people etc. etc. I don't know if you see a therapist, but if you do perhaps you should work through this topic.

I think it's great that you decided to take a course! Good for you!
