Don't worry too much because otherwise you might get sick. One thing I can advise you is that if you don't know something, you will learn it one way or another. I remember when I was 18 and I felt very frustrated because what I was studying was not really what I wanted and I didn't know what my future would be like or if I would survive in this concrete jungle but as the days went by, I learned new things, even new hobbies and hidden talents, when you realize you are already part of something.
