My macbook pro's Start up disk is full. So all process went pause and machine became slow. So I'd force shutdown and now after restart and login, profile is not getting loaded. Please help

Delete some files. You need a minimum of 15% free disk space.

After login, I am getting blank screen(profile not yet not loaded so) , so I can't delete files now at all.

After login , profile has not been loaded yet so I don't think I can delete any files now.
