Is it my intuition or just fear?

I‘m currently in Uni and about to start my internship next month.
I‘m doing my internship in my home country, which was like my biggest dream. I am supposed to leave in like 10 days and I haven’t booked a flight yet. The past two weeks I have been having mixed feelings - like I don’t know if it’s a "gut feeling/intuition".
When I got accepted to my internship I was actually the happiest person ever.
I don’t know why I am doubting things or why I’m having this type of feeling right now. I can’t imagine cancelling the internship. It‘s literally my biggest dream. I get to spend time in my home country, which is basically like a therapy for me. Also my dad lives in my home country, so I will not be living alone. I feel like I am self sabotaging by thinking what could go wrong and I am led by anxiety/fear unconsciously.
But also I don’t know if it’s that or if it’s really my intuition?
I have been avoiding booking the ticket and I don’t know what to do. Why I am having this type of feeling? What would you do in my situation? I really don’t want to cancel the internship. It‘s my biggest dream. I don’t even have considered any other options because of that. I really don’t know what to do…

Is it my intuition or just fear?
