It sounds like you are fluctuating between detached-not-detached. In other words, you're not feeling very strong emotions. Just bland or mildly unpleasant ones.

Am I right?

Like, maybe you enjoyed it better when you were feeling something, even if it was negative. Because the feelings stimulated your sense of self and made you think.

Being detached is an okay place to be, TC. Consider it a holding pattern of sorts. You can use the space between you to be cerebral and questioning. What do you want to change about yourself? Why are you in therapy? What would you like for your therapist to do to help you move forward? I know that you think the attachment is the therapy, but there is no rule that says it must be like this. You can still get something out of therapy feeling "blah" about your therapist and just let the feelings develop naturally, while you're distracted from them.
