Does anyone regret taking a gap year? / Have any advice to make me not regret one?

So I was completely ready to apply last cycle. Good PS, high GPA, great ECs, and doing well on MCAT practice exams. My MCAT was about a month away, then my buddy asked me if I wanted to spend the summer traveling Europe instead. (This was awesome and I don't regret it at all). But because of my decision I had to cancel my exam. At first I was excited to take a gap year but now I don't know. It sucks too see some of my classmates getting into awesome schools and I'm getting a little jealous.... Does anyone regret taking a gap year? / Have any advice to make me not regret one?
