Usage of alprazolam WILL increase the frequency and intensity of a panic attack and GAD over time. Whatever goes up must come down. Doctors love to sell SSRI's, they claim not addictive but they do not tell you about the 2 week (adjustment period) or the withdrawal symptoms most of these drugs have, they can really screw with you. Hate to sound like a snake oil salesman but alternative measures such as breathing, meditation, exercise etc really do help. Just feeling like you are between a rock and a hard place makes it worse. Most people do not understand that focus on a task (landing an aircraft) is the least likely time you are likely to have a problem with anxiety, that social anxiety (too much sensory input and too much time to think) is a completely different problem. I speak of this from my experience, try to avoid the drugs before you make your problems worse but my experience is not everyones. Best wishes.
