I do think that the actual dx's by a professional carry alot of weight, and are very important for proper management. I find it incredulous that in all those forms there wasn't an intake form requesting your history that you said you didn't share.
Please don't wait to begin the medications. Take them to your trusted pharmacist and have "side bar" discussion. Make sure you have your history of therapy and meds in writing while asking about the current scripts. The pharmacist can probably answer all your medication questions.
