The simple answer is - you don't!  Its something only you will know when it happens. However, a certain amount of patience and commitment is required and open, honest communication.
I'm an Registered member of the the BACP (British Association of Counsellors and Psychotherapists) and I operate within their standards.  I undertake regular CPD training and supervision ensuring that my work is safe and ethical.
Counselling is not an Emergency service.  I am not available outside of sessions for any other reason than to arrange or cancel a booking.  If you need immediate help for your mental health, or are having suicidal thoughts please contact the Mental Health Crisis Hub on 0800 038 5300 (FREE).

For medical emergencies please call 999.
I can help you explore difficulties in identifying the feelings you are experiencing and ways to express them. With the right therapeutic approach this can form the basis of our work together.
This is something I will be happy to discuss with you and there is no pressure for you to book further sessions if it does not feel right for you.    
All client information and session content is strictly confidential.  I do not keep records other than contact details which is discussed with you in the Contract during our first session.  
I recognise that talking about your experiences and feelings can be daunting and it can be difficult to find the right words. You may find that drawing or writing things down can help. The Counselling room is a confidential space and the session time is yours.  There is no pressure for you to speak if this is not comfortable for you.
