yes, this sounds rather like one of the fringe churches. Mainstream churches used to teach this sort of thing centuries ago, but they had difficulty making their flock believe it and have gradually let it go. You'll be lucky, or unlucky, to hear mention of the devil in your average Anglican church.
What to do about it, though... I don't know. If the tics (sp?) are in some way voluntary, it may indeed be possible to concentrate on overcoming them. If they're involuntary, all the worship in the world won't help.
