This just means talking to you about your difficulties and your life story, before making a plan with you about what care options would be helpful. You can share as much or as little information by email beforehand as you wish.
The assessment can be at my consulting room or on-line by video-conference. The first assessment appointment can be 90 minutes to give you enough time to share what you need to. If after the first appointment I don’t think what I offer will help you, I’ll say. Usually 3-5 appointments are needed for a full psychotherapy assessment. There will be two outcomes from this: an initial psychological understanding of your problems (a ‘formulation’); and a plan for the care options we recommend.
