I'm very pleased you gained so much from Roger's self confidence course! Ideally it would be wonderful for you to regain your love of learning. Sounds like you were more relaxed about learning when you were twelve, therefore you would have thought about it less consciously, therefroe, yes, it would have been more of an unconscious activity.
The best thing would be for you to continue your studies feeling much much better and more relaxed. Your father has said that you don't have to study and that has taken the pressure off, imagine being able to complete your qualifications whilst feeling much less pressured! This would build your general levels of confidence as you'll always have the knowledge that you triumphed over something you at first found hard.
You need to re-associate, in your mind the activity and environment of learning at university to feelings of calm, focus and confidence. The more you relax and think about where you learn and what you learn the more the beneficial feelings are going to become linked to learning and the more confident you are going to feel.....instinctively.
If and when you get the self confidence cd you'll find that it can help you
different about your studies so you don't have to think
about them so much.
All the best
