You need to devote some time to finding the right therapist as the connection you have with your therapist is essential. You need someone who you can trust, someone you feel comfortable talking to about difficult subjects and intimate secrets, someone who will be a partner in your recovery. Therapy will not be effective unless you have this bond, so take some time in the beginning to find the right person.
It is worth talking to a few potential therapists and asking questions. Therapists also have special areas of focus, such as depression or eating disorders. For some issues, such as trauma or PTSD, seeing a specialist is absolutely essential.
