...but i'm not sure if it was from this show. All I remember is a scene at night where a woman wih a porcelain doll mask tells somebody else "No, it's meeee", in a very crepy way. I can't remember anything else, because I was about 5 or 6 years old when I saw it. If somebody knows, I'd reaaly appreciate it!
I've thought this one over, and it's possible what you're remembering is I'll Never Leave You - Ever/There Aren't Any More MacBanes (1972), from Night Gallery (1969). The segment, I'll Never Leave You - Ever is about an adulterous woman saddled with a sickly husband, whom she has to care for constantly. She would prefer to be rid of him, in order to be free to be with her lover. Impatient for nature to run its course, she seeks out a witch, and obtains from her a doll carved in the image of her sickly husband. She first sets the doll on fire, and is horrified to hear her husband on his sickbed screaming in torment; she then douses it with water, wraps it up, and carries it far out into the fens, and throws it, she knows not where. The voice of her husband calls to her from the marshy fens, and she finally understands that unless it's found and properly disposed of, she will never be rid of him. She runs out into the marsh and suddenly falls headlong, screaming, into the furrow where the burnt, bedraggled doll awaits, arms outstretched, with Royal Dano's face. "Moira," he calls, I'm here! How could I leave you - ever?"
I was wondering if it could be the 1960 movie, Eyes Without a Face? One of the characters wears an eerie porcelain-like mask, although I can’t remember if she said the line you mentioned. Google the movie and look at the images of her.
