Hi I'm Searching for the name of an old series or movie (can't really remember) that I saw on the Hallmark Channel in the late 90s.

It was a horror story about this teenage guy that lived with an evil doll (black&white porcelain type) in his room that told him to do evil/cunning stuff at his school.

I've been trying to look all over the internet for clues to the name of this Movie/miniseries but without no results any help would be appreciated.
