Can't use dashboard since I deactivated jetpack.

I was in WordPress.com and was instructed to disconnect jetpack. When I did this, I expected to see message to reactivate but instead WordPress.com doesn’t show my website. The website is https://susanscreativewritingandpoetry.com and now I can’t use the admin site or dashboard. I tried an earlier backup on Godaddy hoping it would restore but I still can’t use the dashboard even though it shows. I just get a white screen for anything including reinstall for jetpack, css access, etc. Help. Susan
