Wao, it is exactly the same situation I was in last year, I'm 18 now. I had always seen it as a dream, but started to sniff to it as a serious career.
I was also sure that I should go to university, but the idea of studying more, after 15 years of schooling, was not to overcome, so I'm sure that flying is what I want.
In addition, I also took some unofficial flying lessons, so I had an idea of how it is to fly myself and found it fantastic.
But good luck
