First of all, I would contact the College of Physicians and Surgeons for your area. If you have a case, they will initiate a grievance and provide you assistance (I lodged a claim against a previous psychiatrist and it ended with a serious reprimand against her).

There is the additional route of contacting your Ombudsman.

If you work, your employer should have an EAP (Employee Assistance Plan). Most plans provide for up to 3 free consultations with lawyers - which they will also set up for you.

Most larger municipalities provide for an 'centralized intake' where they can refer you to services including legal.
