Dying Christmas star: can it be recovered?

Question: Dying Christmas star: can it be recovered?

Last year I was given a deep pink poinsettia: between spring and summer it made a lot of leaves, it looked like a bush. The trouble started in September: the leaves had white spots, so I sprayed with the antimicotic that burned them. With frequent washing, most of the leaves recovered and new ones were born.
In October I brought the plant indoors and began to cover it to color the bracts: within two weeks the leaves became yellow and soft, although I did take light to the plant anyway. I was advised to place the plant on the windowsill, between the inner and outer glass, but evidently it was too cold and now the plant looks dry. I brought it back into the house, in a less hot room, away from heat sources. It has some gems that show no sign of wanting to sprout; a twig that looked green and alive softened.
They tell me to throw it but I can't, I'm fond of my star: do I have any hope?

Dear Anna,
probably this Christmas star cannot find a good climate suitable for its development; in fact the care you have given so far would be the right ones. Perhaps you have exceeded in watering, which must be provided only when the soil is well dry; or perhaps you have not provided the right fertilizer, which should be done at least every 15 days, with fertilizer for flowering plants.
