There is no jury duty where I am from but I could imagine, with my anxiety levels, that I might have experienced a similar thing. It must have been very terrifying for you. It is good that you sought help as quickly as possible. You are still in the early days of your medication so it is very possible that you could be feeling side-effects. I can say though, that I also experience a very "unreal" feeling, even long after a panic attack.

I hope you continue to go from strength to strength.

And welcome!
