I think your psychiatrist was way out of line saying that to you . If you lived in the States, child services would have taken you out of that toxic environment a long time ago. Is there a service that can help you navigate in society?
It would be such a waste of talent and compassion if you didn't use your skills to become a doctor. You can do anything you want! Once you're an adult, get out of that house, find some services to help you , and take the exam...then laugh in all their faces when you succeed.
