You are definitely entitled to have a copy of your entire file; usually you just have to request this through the medical records department. I have in rare cases told the records department NOT to give records to a certain patient (usually someone with severe schizophrenia...because reviewing the records would only anger them).
You have every right to your records and they must give them to you (but there could me a wait involved...they don't have to provide the records immediately unless there is a true emergency). Let me know if you have other questions.
Good luck & take care.
I'm not sure exactly why they would...the only time I've ever done it is with schizophrenic patients who are in complete denial of their illness because reading my reports about them being delusional would anger them at me and also weaken our therapeutic working relationship.
As far as I know, this policy is usually only used by psychiatrists (not other types of doctors). I hope that makes sense. Let me know if you need more clarification.
