The analyses of a text #3

The narrator recalls his childhood.
His nurse Peggotty was married to the coachman Mr. Bariks.
And he visited Mr. Bariks' for one night stay.
Now Peggotty tells him the room where he slept is to be always his.

"Young or old, Davy dear, as long as I am alive and have this house over my head," said Peggotty, "you shall find it as if I expected you here directly minute. I shall keep it every day, as I used to keep your old little room, my darling, and if you was to go to China, you might think of it as being kept just the same, all the time you were away."
I felt the truth and constancy of my dear old nurse, with all my heart, and thanked her as well as I could. That was not very well, for she spoke to me thus, with her arms round my neck, in the morning, and I was going home in the morning, and I went home in the morning, with herself and Mr. Barkis in the cart.
[David Copperfield by Charles Dickens]
I think if "spoken" is implied after "very well."
If so, I'd like to know if the reasons why he didn't expressed well are the following.
1. Because she spoke to me thus, so that he was deeply moved.
2. Because her arms was round my neck, so that he felt suffocated.
3. Because he was going home in the morning, so that he was sorrowful.
Thank you in advance for your help.
