Admin login screen and some pages gone

My site was apparently hacked a few days ago. The homepage of my site appears fine, but when clicking on any posts it goes to a blank white screen. I also can’t login because my wordpress admin login page is a blank white screen.

I’ve been going back and forth for 2 days with my web hosting support…of which they are no support at all and also telling me they have been having backup server problems so can’t restore anything.

My googling has not been very helpful…maybe since I am not very tech savvy.

Can anyone please tell me how I would be able to access my wordpress admin login screen again or get it to appear? I don’t know what steps I might be able to take within my cPanel.

Thanks so much for any assistance.
