Is it possible to learn play the violin by yourself?

Without an instructor, only internet and some music sheets.

I learned to play the guitar all by myself and only know how to read tabs, not music.

My mom kept saying me that it’s no use since we can’t afford to pay me an instructor if ever i have bought the violin. But i really wanna learn to play it.

So.. is it possible?
