Obviously the best person to answer this question is the doctor prescribing for you, preferably a psychiatrist, but perhaps a GP, as he presumably knows a lot about you, your precise condition, previous medical history and responses to drugs, I have no idea why you'd be on Urbanol, though some doctors seem to have developed a passion for prescribing it. It's a benzodiazepine sedative tranquilizer, originally intended for use in treating epilepsy. It is not recommended that any benzo be used for more than a couple of months for conditions other than epilepsy, a=due to a risk of developing dependency. And as Lexamil ( Escitalopram ) is considered an adequate treatment for depression and anxiety, I wonder why you needed the added sedation.
Anyhow, an acute infection might have worsened the symptoms you mention, And I'd be especially interested in what drugs if any were prescribed for your sinusitis and fever, and what drugs available over-the counter without prescription, you might have taken then. Several of those available could interact with your other meds, and could in their own right cause symptoms including nervousness, palpitations and anxiety.
The CBT should be useful, anyway
