"I'm worried about not sharing enough in the first session"
Don't worry, in the first session it is about getting to know you, what has brought you here, a bit of a background and of course a few forms to fill in, time will fly and there is never any pressure to share anything you are not confortable with.
"What if you think my problem is silly and not a big deal?"
It is not my place to judge what you bring, if it is important to you, it is important to me. In life different things will effect people in different ways and we all need space to process what has happened or why we feel the way we do, I will probide you with the space to explore what is going on for you.
