Before your appointment, write down important points you'd like to discuss with your doctor. This way you won't forget any relevant information you need to impart. For example, you can include frequency of the anxiety attacks or whether it is chronic generalized anxiety. If any event initialized the anxiety, you should discuss this too.
Write down questions you want to ask. Questions may include treatment options, types of pills available and their side effects and whether anxiety may be caused by underlying diseases (adrenal disorders, for example).
Bring the notepad with the comments and questions to your doctor's office when you go. Also bring a pen or pencil so you can take notes (about treatment options and advice) while you are in the office.
Be honest with your doctor about your symptoms. If you withhold information because you feel uncomfortable talking about it, such as a history of trauma or abuse or a recent death in the family, then you likely will not get the help you need because the doctor will not have the pertinent information.
