Freedom is going through much the same thing as you did; I so feel for both of you.

I think it is only natural to get upset...he WAS your dad, and plus, just the release of stress from all those years.

Yes, I am sure your dad is walking and speaking, hearing, thinking and more!

As to going back to what you were before, I never did after my dad died.

"What I am to be I am now becoming."

And take your own time getting there.
