Googley, a therapist can evaluate a client and see if the needed work is superficial or deeper work. She is acting correctly by realizing gaps between what is needed and what she can do. If she is a campus counselor, she doesn not have experience with deeper therapy, especially if the rule is 12 sessions.

You asked to just work on anxiety, a tip of the iceberg, but she can probably understand that there is more to the iceberg under the water. You deserve good therapy Googley.

I think that there is some triggering going on. You have an expectation that you are going to be sent away and people want to get rid of you because of how you grew up. You are trying to fit this trigger into what happened with this T because this is the treatment that you expect.

I am assuming that you didn't explore the topic with her because your urge was to run away from it but talking to her about your options could be productive.
