Gecko not eating, looking at reflection, tail is getting skinny!!

My leopard gecko has just recently stopped eating her usual diet and she's been very interested in the background of the vivarium and her reflection in the glass. I considered if it was any type of impaction since I haven't seen her excrete in 3 days. Looking for help! I tried massaging her stomach in some lukewarm water. She usually loves to eat her food.
