Perhaps you used a save from a previous version of the game, and when launching the updated version with a number of shifted variables, the developer failed to process them correctly, and they are now misplaced. Perhaps you decided to "unravel" the story along your own unique path, and the developer didn't appreciate or anticipate this. There are many ways to stall this game.
In your case, you can press the gear button on the phone icon (Change Setting), click Cheat in the window that opens, then type doctor (on the keyboard) at the bottom of the screen (Input Code), and press Enter. Then press Return and exit to the city map. I have no idea where the story will take you, but at least you'll get out of the dead end...
You still won't be able to get into UNIVERSITY (because your save has Sisterhood.Level = 0, don't ask me what that is), but perhaps as you continue playing, you'll be able to develop relationships with other characters until you're allowed to join a fraternity (or sorority, whatever that means)... Good luck!
