Stress and anxiety about my future is not letting me be happy for even a moment.

I have mock exams almost every sunday and most of my peers do who are prearing for med school entrance but even if i take breaks or try to enjoy myself in the process, i just can't. I feel so much more stressed and anxious than most people that i can't enjoy anything.

I have this constant fear that i won't end up anywhere and it's a constant battle against my mind everyday. I have tried processing my thoughts and living in the present, but nothing works.

I just want to be able to study and not feel like this.

What's even more depressing is that i used to be so excited for my birthday months before and im turning 17 in 2 weeks and it's dreadful.
