If one talks about how one "has no one" or, "feels like everyone is against me" then the leap to, "you must be feeling alone" is just a restatement of what you've said. It's not a guess or a question or anything, just putting their understanding of what you've said in their words to see if how they see it meshes with what you've said. I was notorious for changing :-) and never letting my T get it quite right. But that's what I was in therapy for, to learn how to be comfortable on the same page as someone else without thinking I'd be swallowed up or something.
