As others have said, it can be both. I don't see how they can be confused (one produces symptoms independent of environment and the other produces symptoms based on environment/trigger), but I guess a pdoc who isn't paying attention would not ask the right questions to sort it all out.

And you don't have to reveal any details. At least, I didn't. My pdoc asked me general questions about trauma--did I ever experience one, did I have flashbacks, nightmares, and do I avoid certain situations. She later came back to it and asked what had happened, and I said I would not talk about it. She kept my primary dx the same as it had been, which was bp, but added PTSD. It wasn't her job to counsel me and she knew that, so she didn't press for details. All she needed to know were the symptoms. I hope you can find a better pdoc who will ask the right questions.
