Joanne, there is a method of getting this bush back to a smaller size.
If you use a mix of 50/50 sharp sand and compost, pile it over the base of the bush to a depth of about 6 inches now. By next summer you should have new growth appearing from the bottom, you can then cut the top growth away and resize it if you wish. It does work, you just need to be patient and not cut back till the new growth appears.
