I am sorry to hear about these issue. Obviously they would require to be investigated. However, most of what you have mentioned can be seen as forms of abuse, in this case you need to report tis to the police. You will not take legal action personally, this will be passed to the police, if charges are broght abasing the organisation or individuals, they would be prosecuted by the CPS. There is sometimes victim compensation, but that would come after a prosecution.
