"Feeling alive"

What expressions does Rita use to emphasise how important the course is to her?

"But its not takin' the place of life, it's providin' me with life itself."
"Comin' here, doin' this, it's given me more life than I've had in years,... Well, if he doesn't want me when I'm alive I'm certainly not just gonna lie down an' die for him."
"I've begun to find me-an' it's great you know, it is Frank. It might sound selfish, but all I want for the time bein' is what I'm findin' inside me."
To Rita the course is so important that she compares it to the breath she needs to live. Under no circumstances will she give up the course because it helps her to discover the person there is inside her.
