It can be a minefield finding the right counsellor and google will show you so many in your area.

The first step is finding a registered and accredited counsellor with governing bodies such as

The British Association for Counselling and Psychotherapy (BACP)

United Kingdom Council for Psychotherapy (UKCP)

The National Counselling Society (NCS)

Addiction Professionals

College of Sexual and Relationship Therapists (COSRT)

Each governing body will have a register of accredited counsellors and you will then be able to search by location and specialisms. It can be helpful to focus on the therapeutic approach you are seeking for example, CBT, Integrative Counselling or Psychodynamic. The issues you are seeking support for such as anxiety and depression and any specific needs you have regarding the counsellors experience in working with diversity.
