Anxiety is about the future. You cannot know the future. Therefore, all of your thoughts about the future are in your head/imagination. So, imagine good thoughts about the future, if you must think any at all?

You are afraid you will not get your degree; how old are you? I got a degree, in the subject I went to university to get when I was 18, at the age of 57. You have your whole life to get your degree if that is what you want. If you don't want it, then you will do something else. Your life is about what you want to do.

How can what you are doing be wrong for you? You are doing it. Only you can know what is right for you and what you want to do. Maybe you will find work and maybe you will not find work; you cannot know until you are interested in finding work and pursue that goal. Right now you are studying?
