A lot of people are very nervous about their first visit to a therapist. Whether this is their first time in therapy or if this is the first visit to a new therapist, it can be very nerve-racking!
It may take some pressure off to realize that a first visit is a time for both client and therapist to get to know one another. There are no obligations at this point to have further sessions. If you like the therapist, then you can schedule a another appointment. If you do not care for the therapist, then you can let the therapist know that you do not feel it will be a good match and keep looking for someone who you think will be able to help you.
Doing anything the first time is often uncomfortable and difficult. Usually, with time, things get much easier. Be brave and make that first visit. Remember that it is your choice if you continue in therapy.
