As I think that you are already well aware, a psychiatrist is a medical doctor. Being medical doctors, most of them are no longer involved in the old fashion "couch" therapy sessions. After an intake interview, my lasted an hour and 20 minutes, a psychiatrist can provide you with an actual diagnosis, they can write prescriptions for appropriate medications, and also design a treatment plan, specific for your needs.
One thing that your psychiatrist will take into consideration is your history. Mine indicted a history of mild anxiety problems that became more severe some four years ago. With this to consider, I was started on an anti-depressant, and plan on being on one the rest of my life.
I don't take "as-needed" medications such as the benzodiazapines, but you can be on an anti-depressant, such as an SSRI, and still have a "whenever necessary" medication, such as the benzodiazapines, for when things get a little stressful.
Do keep an open mind when you see your psychiatrist tomorrow. They have trained long and hard to provide you with an appropriate route of treatment.
The very best to you, Potatoes!... Chuck
