Remember, the circling approach that you practice in the simulator is just that, each simulator is certified for a particular circling approach and it doesn't mean that is the standard to apply in the real world.
In the real world circling approaches that I have done it was done in a non radar environment with others holding until you landed.
If the weather was a factor on your approach then we would request a straight out departure if feasible from ATC in the event of a missed approach.
But if you don't request it then you must circle back towards the instrument runway and fly that procedure which could be a handful on a A320 especially since you activated the secondary and now have NO MISSED APPROACH PROCEDURE in the box, woohooooo, good luck. Smart money pilots only activate the secondary when on short final
