Good for you Alpha. You're right about discipline. It is an important element. It's also useful to ask yourself whether what you are about to say or do will get you closer or further away from your end goal.
Normally when we give into our emotions and so something daft (been there :-)) it takes us further from our goal. And that's where the discipline and self control come in. We override our impulses and respond to things in a measured way.
I think you're probably right about the shock too. It takes a while to come to terms with what has happened. But, like so many of us - you're moving forwards my friend...
