Who Commissions Support for Survivors?

Like many who have been sexually abused as children I suppressed the memories of the abuse for many years as a self-protective mechanism. It was only in the last couple of years that I have found those memories and feeling beginning to surface despite my best efforts to keep them down.
As they did my own mental health deteriorated and I began looking for support and help only to find that there seemed to be no help tailored to Adult survivors of abuse available in Somerset. Even that provided by charities was sparse and focused in the bigger cities.
This prompted me to begin asking questions believing that either the NHS or Local Authority would be responsible for the recognition of the need for such support and its provision. After finding little or no information on the web sites of wither the Clinical Commissioning Group or the local authority I decided to ask, via a freedom of information request, what provision they had in place and what their planed provision was.
