Hi, I'd like to help you with your question.
There is nothing wrong with you reading the report from the psychiatrist. It is about you, you paid for it, and you have the right by law to see it. But, given that it is a medical report, you need to keep in mind that it is written from a psychiatrist's perspective. It is their job to give the best impression they can of a person they see for an evaluation. What goes into that is their impression based on their education, perspective, experience and their own interpretations. The psychiatrist may be a good one or a bad one. Also, it is written with the assumption that the patient will not read it. So most doctors do not hold back if they even suspect a possible issue with the patient. All those factors come into play with the evaluation.
Your doctor is right, in a way. Reading the report alone is not a good idea. There is no way for you to know the reasons behind the things the doctor wrote, and to understand why makes a big difference. Instead, you may have read the report, but with your doctor sitting with you and explaining what you were reading. That would have helped you get a better idea of what you were reading and why the doctor said what they said. And keep in mind, this is one doctor's impression after meeting you for a short time. Just because they said it, doesn't mean it is true. It could only be partially true, or not true at all. So try to clarify it with your doctor so you can get a better understanding and feel better about what you read.
I hope this helped you,
