You don't say why you're taking the alpha blocker, and you're posting in the anxiety forum but taking Cymbalta, which is usually used for primary depression rather than primary anxiety as its effects on norepinephrine you're talking about can be very stimulating -- intentionally so to get depressed people going again but can cause anxiety because of this. None of us on here are pharmacologists, so this is a question for your psychiatrist or perhaps a pharmacist.
