I don't quite understand you. What do you mean by you deleted your blog? And on the one hand you are saying it is showing up on the broken themes list, while on the other you are saying this is the only theme you can use. Can't you get the default theme (Kubrick) working?
You can try deleting the folder for Suffusion and manually upload the directory via FTP. For that you can download the theme from http://wordpress.org/extend/themes/suffusion
and unzip the file to get a "suffusion" folder. Then move the whole "suffusion" folder to wp-content/themes/
