Cool. Not a bad move at all. Now leave it at that. I suggest read up on the validation cheat sheet again a few times because you'll probably need it a lot where you're at right now.
Not to undermine what you said, but try to mirror her feelings when you validate - trust me, it took me a while to get it right so this is no means a dig on you. I would've said this:
"I understand you're feeling overwhelmed. This is a difficult process".
Now I am going to go enjoy the rest of the day. I hope you are too.
