Understanding you
The first stage is a conversation, and it is longer than most people expect. Before any technique is considered, the work is to understand the situation as you actually experience it — not as a category, and not as the sentence you rehearsed on the way here.
That means talking about what has been happening and for how long; what makes it better or worse; what you have already tried and what happened when you did; how it affects work, sleep, family and your view of yourself; and what you would like to be different in terms concrete enough to be recognisable.
Two things are decided here. The first is what we are actually working on — which occasionally turns out to be adjacent to the presenting concern. The second is whether hypnotherapy is a sensible approach for it at all. If it is not, you will be told so at this stage rather than after several sessions.
