IcantdoitI would suggest you may have better luck seeing a psychiatrist as they are the experts in prescribing mental health medications.
I understand way to well the horrible feelings anxiety causes and when your locked into anxiety nearly all day long you pray for a medication to help you.
I suspect your Dr. should have prescribed the ABX for your infection and something else for anxiety until you recovered from your respiratory infection.
Do check out our resources at the top of this page as there are many great topics as well as self help info that may help you through this rough time.
Kindly,
