Don't feel badly at all that it takes a while to digest everything at such a time as this meeting with your father. I and many of the other men have experienced that same thing. Somehow I had the idea that once I'd done something of significance as you've done that I'd have it all figured out and tlhen move on from there.
In my case nothing could have been further from the truth. I "digested" as you say, the event/s for days, weeks, and months afterwards and looking back I can see where those moments in time had profound impact on my recovery which I could not see immediately afterward. I used to beat myself up for that. Now I realize it's all part of the process.
The healing comes sometimes in almost inpreceptable increments and sometimes I think that is the best way as it has "staying power". One awesome thing tho is that during that slow growth we tend to have these really cool "light bulb moments" where something suddenly dawns on us and those we sure do celebrate!
Have a successful business trip, Bro.
Lots of love,
