Hon, I think you've missed the elephant in the room - the drug WAS your problem! You had anxiety about a heart scan - a lot of people would be anxious about that, but it doesn't mean you have a "disease" that needs treatment with a powerful psych drug! If you read through this forum you will find soooo many people complaining of severe anxiety on start up of these meds! So, then your doctor tried to treat a drug side effect with another psych med, mirtazapine!
