The patient who had a two-year sexual relationship with Chancellor George Osborne's psychiatrist brother has claimed he used her as a "sex toy".
Dr Adam Osborne was struck off from the medical register after the Medical Practitioners Tribunal Service (MPTS) ruled that his fitness to practise was impaired by reason of misconduct.
MPTS panel chairman Dr Nigel Callaghan said the married doctor's affair with the patient, who he had been treating for depression, anxiety and chronic fatigue, was "profoundly unacceptable".
Speaking to the Mail on Sunday, the woman said she had become "dependent" on him after receiving therapy for two years before the sexual relationship began.
She said: "I am happy that he cannot do that to anyone again and I am happy that my story was believed, but I don't think I can ever be happy about Dr Adam Osborne because that man was responsible for too much trauma.
"He treated me like a sex toy. I don't think he has a conscience and I don't think he cares about anyone but himself. I am worried and anxious that he will think it is safe to contact me because now he is struck off there will be no further consequences.
"He does still have a hold over me and that's why I am scared about him trying to contact me."
The woman, referred to as Patient A, attempted to take her own life two days after Dr Osborne ended the relationship via email.
The tribunal heard that he bombarded her with threatening emails over a 10-day period begging her to retract her complaint to the General Medical Council (GMC) detailing the affair.
Dr Osborne had treated the woman at a private practice in central London from February 2011 until late 2014.
He admitted the allegations and said he fully accepted the findings of the Fitness to Practise Panel.
In a statement after the hearing on Thursday Dr Osborne, who is five years younger than his brother, said: "It was never my intention to hurt anyone although I can now clearly see that my irresponsible behaviour has led to a great deal of distress to the people that I care about, in particular my family and the patient in question.
"I realise that there is never any justification for breaking the boundaries of established good medical practice in regards to the doctor patient relationship, and it is never in the best interests of the patient to do so.
"I have found medicine to be a very rewarding and fulfilling career and I am very saddened that this career is now inevitably over."
In 2010 he was suspended from practising medicine for six months after writing fraudulent prescriptions for a girlfriend, a family member and an escort girl while a psychiatry trainee at Wythenshawe Hospital in Manchester.
