My Phal Valentine's Gift is sickly

[kiki-do]

I had two spikes chock full of gorgeous blooms that lasted for months and months. I cut the two spikes back when I was sure it was finished. Two more growths started from those two cut spikes. Then as the new growths were coming on, my leaves started turning yellow and falling off one by one. I have one leaf left and it's yellowing. I repoted and the roots looked good, way back when the blooms had gone by. Any hint of what is happening? I just watered the plant today so that is why it looks wet.
