Why not go to this place, get the tour, talk directly to the people in charge, find out what it is all about, etc. and then decide? In the meantime, keep seeing you current therapist. You don't have to make up your mind right away.

I'm sure it feels abrupt and sudden. It is probably something she just discovered and immediately thought you could benefit and wanted to let you know about. It sounds like she just wants to help you find whatever it takes to help you through this.
