There's no sure-fire test, like a brain scan or anything. Since you mention "results" I wondered if you might think this. It might be nice if such a thing existed(!) It's just talking. Anneinside covers what it will actually be. Just be honest about what is going on. They will likely ask some questions to clarify some things. Don't worry though, if you've got stuff going on, they are there to try to help make it better for you.
