Try to relax and be yourself, whatever you are feeling. If you're a little nervous, then express that. They'll probably tell you a little about themselves, degree, license, philosophy of counseling. You could ask them if they have experience with people with borderline disorder, depression, etc. if that's something you're wondering about.

It does take awhile for the two of you to get to know one another. For me, I started with my history from my suicide attempt and hospitalization up to the present, which at that time was about 9 months. Then I launched into my present issues and concerns.

It's an interview of sorts for you as well to see if the two of you 'click.' You'll know after a few sessions if this is someone you can feel comfortable with. Luckily, for me, I knew right away. My criteria was for my therapist to be kind and non-judgemental.

I'd suggest you go at least a half-hour early because usually there is a lot of paperwork to fill out. My current therapist had insurance forms and payment forms, and policies to sign, as well as a little survey about my 'problems' and current needs. Oftentimes, these little surveys can be a starting point for your first discussion.

Just be honest with however you are feeling at the moment and let us know how it goes. You'll be okay. Remember it's their responsibility to help you.
