quitting the piano

I played like 4 years when I was little then started back again made quick progress its been two years but its frustrating because of my teacher pushing me into believing I am better than what I am I am with impossible songs 5 months in liebnaustrum then mozart sonata 8 and I just feel like I am terrible at it I love music I just wish I could be better but even though my reading and technique is getting better it is just frustration that I am not as good as what I listen to this perfectionism is just killing my mental health is it worth it to quit for a while ?
