Deleted Themes Folder from Cpanel and can't to upload themes & can't see my site

I tried to upload breadcrumbs code in functions.php !!
Before pasting the code, I copied the whole functions.php code and pasted it in my notepad !! Later when i pasted breadcrumbs code and saved it !! I was getting some parse error missing at line 24 (something like this )!!

Then immediately i deleted the whole functions.php code and the pasted the one from my notepad !! It showed the same thing again !!

I felt that i messed up something !!

I have tried this a lot of times but was getting the same thing !!

Finally i opened my cpanel>public html>wp-content>themes
The mistake i did was, instead of deleting a particular theme i have deleted all the themes!!

Now i can’t see my site,can’t upload a theme !!

when i try to upload a theme in wp-dashboard it says directory is missing !!

here is my site address : https://www.rebeltrends.com

please help _/\_ !!
