Requiem for a Dream (2000)

Continuity mistake: Harry stands on top of a building with a girl folding paper planes. The plane they fold is folded with a blunt front. He throws it off the building and then the plane flies, all of a sudden the nose is sharp, this is visible. (00:12:10)

Sara Goldfarb: I'm somebody now, Harry. Everybody likes me. Soon, millions of people will see me and they'll all like me. I'll tell them about you, and your father, how good he was to us. Remember? It's a reason to get up in the morning. It's a reason to lose weight, to fit in the red dress. It's a reason to smile. It makes tomorrow all right. What have I got Harry, hm? Why should I even make the bed, or wash the dishes? I do them, but why should I? I'm alone. Your father's gone, you're gone. I got no one to care for. What have I got, Harry? I'm lonely. I'm old.
Harry Goldfarb: You got friends, Ma.
Sara Goldfarb: Ah, it's not the same. They don't need me. I like the way I feel. I like thinking about the red dress and the television and you and your father. Now when I get the sun, I smile.

Trivia: Director Aronofsky requested that Leto and Wayans refrain from having sex and consuming sugar so that their cravings and drug addiction would appear genuine on-screen.

Question: [Spoilers] What exactly happens to Sarah Goldfarb at the end? Some people say she's in a catatonic state, but she seems to be functioning too well for that. Can someone please explain the situation she's in after the Electric Shock Therapy?
