Hi,i'm A Male,31yrs Old. I Have Anxiety Disorder And Panic.

Hi,i'm a male,31yrs old. I have anxiety disorder and panic. If I take stalopam plus 5mg.i will not have any fears nut it has few side effects like reducing sex drive. And I don’t have depression. So it is a good idea to take benzodiazepines instead of stalopam?
Please advise. My marriage is coming up in next 2 weeks, so I would like to have some medicine to reduce my panics.
