Does being Emotionial generate new sankaras?
You just finished a retreat. Give everything time to settle down. Currently, you are taking it all far too seriously.   

Obviously, you had an arduous experience. Tears of relief; possibly some catharsis. There is no need to be concerned. 

Give 'anicca' ('impermanence') a long term view; such as one month for those 'sankharas' to settle down. 

'Sankhara' does not (exclusively) mean 'intention'. 'Sankhara' is any kind of mental formation, including non-intentional or automatic instinctual emotions. 

For example. when the mind goes into 'shock' due to an accident, this is not intentional. 

Similarly, during an intense retreat, emotions will arise that are not intentional.

It appears that a few emotions, more or less, is not going to increase or reduce the sankharas stored within your mind in any significant way. 

I suggest, for the next few weeks, to forget the teachings you heard &amp; return to some ordinary activity, particularly some physical exercise to burn off &amp; settle the emotions &amp; hyperactivity.
