Answer

She had had the same feeling, every week, since she was a little girl.

Answer

Here, "same" acts as a pronoun. You can use "so" in the same way:

"It was so week after week".

You can also say "the same thing" (in which "same" acts as an adjective):

"It was the same thing week after week".
