I tend to agree with Anne here: I don't see attachment as some "thing" to "get." Nor do I see the point in striving for it, even if it were possible to do so consciously. At times, it seems like more of a distraction for you from looking more deeply at yourself and how you choose to live your life. What is it that you think will be achieved by gaining such an attachment? What is it in your life that will be possible for you once this point is reached?

My experience has been that therapy only impacts life outside therapy when accompanied by steps taken outside of therapy. The t/client relationship can be the tool, but it isn't the goal. You've stated pretty clearly that you neither expect nor desire your life/self to change. Supportive therapy is fine, yet you seem dissatisfied with that as a rationale; so what is the therapy reward for you?
