What you've written sounds totally normal to me. I just went through it last week. Starting with a new therapist is tough, because they do need background information and to get to know you somewhat, when you may be chomping at the bit to get to the therapeutic part.

I saw a new therapist for the first time last week and came away concerned, worried that I was having some reactions to her that were going to get in the way of my therapy. I spent a few days considering other therapists, and finally decided to give it 3-4 more sessions before I made a decision.

I just went for my second session, and it was productive and interesting. It's still early days, but I'm hopeful.

You might tell her about your reaction last week to see if she can help to slow down the pace of your session. There's only so much we can do in one session, and I find it's better to concentrate on one thing and gain some constructive insight about it than to hit a lot of different painful issues.

Best of luck today (or tomorrow) - not 100% sure based on the time you posted.
