No problem. Here is information about the data protection act http://www.bacp.co.uk/terms/dataprotection.php
And here is information on how to make a complaint to BACP http://www.bacp.co.uk/crs/complaints.php
Linked from that page is a free advisory service called 'ask Kathleen' which may be able to provide more information. I think you have grounds for complaint, not least under the BACP ethical principle of trustworthiness, which she appears to have violated on a number of occasions with you.
I do want to emphasise - please take care of yourself first and ensure that you have adequate support in place to deal with all of this. Best wishes
