Neutrino - Yeah, I would definitely emphasize that to my psychiatrist if I were you. Let him/her know that your concerned that they may not be identifying the chronic nature of what you've been experiencing. And then, if they disagree at least you have the right to have them explain to you why they disagree. They may see something that we're not getting here online.

And sometimes diagnoses are changed for insurance purposes or some other factor like that. For example, If insurance won't pay for a certain diagnosis, or if the agency has a set way of dealing with a particular diagnosis that the psychiatrist disagrees with in your case, they may change your diagnosis so that they can give you what they feel is the appropriate treatment (even though you're now labeled with an incorrect diagnosis).

Just keep all of this in mind when you talk to your psychiatrist, and remember that you have the right to ask questions and understand why they do what they do. After all, it's YOUR treatment, not theirs!
