Rrejections

I just got rejected from an internship I applied for. It was a 10 week internship to work in an university lab and you get paid as well. It would have been an amazing opportunity for me. But no. Instead, I'm starting to have a line  of "rejections" in my career life. I always seem to get rejected from high end jobs like  I don't belong there. I feel like I'm not meant to be amazing things. I really wanted that internship. I feel so sad. What am I going to do now?  I have exams coming but I need to stress about finding internships in a lab as well.
