Hi there Daycia and welcome to the Psychotherapy forum. I think that each appointment and each therapist are a little different, but I think it's very common in a first appointment for the therapist to ask you what brings you to therapy and let you tell them a little about yourself.

It's also an opportunity for you to ask any and all questions from what appointment slots they have open to what style of therapy they provide to whether they give hugs (if you care to know, haha) and anything else you think is important. I think it's important to see someone experienced with your issues who plans to be around and practicing for a while. I even like to ask the therapist if they have had therapy as it helps a bit to know they've gone through the process.

I do suggest you try out at least three therapists: you have no obligation to continue meeting with a therapist just because you have an initial appointment with them. You'll be doing intimate work and want to make sure you click with the therapist.

Good luck with your appointment tomorrow!
