If you haven't already, ask for clarification from whatever mental health pros say you have "attachment issues." Just straight up say something like, "Can you clarify what you mean by 'attachment issues'?"

Any phrase of "____________ issues" is fairly vague. That's usually the point of the phrase, I think. The vagueness allows it to be used to refer to multiple things collectively and also gives a way to refer to problems that haven't been thoroughly identified. But the downside of vague phrases is that they are less self-explanatory, so I think they should be prepared for you to ask for further explanation.
