I think this might stem from the fact you've finished your academic studies for the first time in your life. You studied CS and you proved you're capable of learning to a high standard AND you achieved a great result. Now it's up to you to choose what you study next. What areas do you feel you are missing? Even outside of tech. When you leave uni it's not possible to have studied every concept. I did CS in the UK too and I went down the analytics, data, ecommerce route and left with very limited programming skills. That's something I've had to address since leaving. Follow your interests and plug the gaps that are worrying you.
