Honestly, just take a few deep breaths. It's going to be fine! What helped me was reminding myself that there was very likely nothing I was going to tell the therapist that they hadn't heard already from someone else before.

Typically, the first session is a "Get-to-know-eachother" session. You won't be doing anything deep most likely. I've seen quite a few therapists while I was trying to find some that I liked, and almost every single one reiterated that I didn't have to talk about anything that I didn't feel comfortable with. Especially if you tell the therapist that this is your first time ever in therapy, they will try to do their best to put you at ease.

As for needing therapy or not, that's really up to you. But you decided to give it a try so perhaps there is a part of you that thinks you could gain *something* from it. I would say just go in with an open mind. Maybe you will discover things that you want to work on that you never considered before. Or maybe you have something specific in mind that you want to work on. The therapist should be able to help you identify why you are seeking out therapy as part of this first session.

Good luck! Let us know how it goes!
