Hello @rosibelsac :)
What a beautiful, insightful comment you left for me here!
Thank you so much for discussing the treatment you underwent as a child. It is this sort of information that promotes a better understanding of what psychology entails. It is through acquiring understanding that we can diminish prejudiced views not only about psychology, but also about mental-illness.
As far as I know, there isn't a branch or a field called negative psychology. The study of the human path towards self-actualization is called positive psychology and its opposite is termed either Traditional psychology or psychology as usual.
As for the difference between psychiatry and psychology, here we go:
Psychiatrists are medical doctors who specialize in the treatments of mental-illness. Just like a cardiologists is a medical doctor who specialists in heart conditions.
Psychologists are mental health professional who study human behavior and mental processes. They cannot prescribe medication. When a psychologist sees a patient in need of an anti-depressant pill, they refer that patient to the psychiatrist. They then work in conjunction, one providing therapeutic care and the other the medical care.
Hope this has helped you to understand things better :)
All the best for you.
