Hi Cream Cheese,
I'm so sorry you're going through this.
I don't believe you're doing anything for attention either, and it really sounds like you need a new t.
For someone just starting therapy, asking what people normally get out of it is a perfectly good question!
I think every person probably gets something different out of therapy. For me, it's all about the relationship. Feeling safe with the person, like you can share about your life, or just be in the room, however you are, and the t will validate your feelings, and be there for you in a nurturing supportive way. Everything you do I believe has to start with this foundation, which obveously isn't there with this therapist!
I actually would not recommend talking to this person and trying to figure things out. She sounds so unprofessional that I'm afraid she would make the situation worse. You talked about problems with talking, I'd hate to have this stress you out more. I'd just leave and try and find another more supportive t. Look online, psychology today is great. Or talk to your GP, either the school one, or at home, for names.
Then get a sense of how a few people are, and then you can choose which one would be best. Feel free to tell them about this experience, it might help a good t to be even that much more sensitive to you and your needs if they know that all you're going on with therapy is this bad experience.
Let us know how things go!
