how far will I get in Israel only speaking Yiddish?

For some reason this post was removed from r/Israel so I’m posting it here

Hi! I’m due to move to Israel next year and I am just wondering if I will be able to survive with only fluency in Yiddish. I can read Hebrew but I do not speak it and although I understand some phrases, my last few trips to Israel made it quite difficult to navigate around. However I am going to Jerusalem this time and I was just wondering if there were any places that still spoke Yiddish or where the language is still alive? Thank you in advance.
