Help identifying Christmas cactus disease or damage please

[Bumpusismydog]

I have had this, what I'm assuming is a Christmas cactus (pink blooms in winter) for a little over a year. Over the summer it began developing these issues with the leaves. I think it may have had spider mites at a point (I haven't seen webbing again in about a month, have treated twice), it has also been knocked over by dogs and I believe I was leaving it in too direct a light. It bloomed in the winter and is putting out some new leaves. I haven't fertilized it. Other than epiphyllium virus I can't find anything online that resembles the problems I'm experiencing, but with as much as its been through I'm just not sure what to think or do. Any ideas? Thank you for the help!
