These plants are very bright light plants. Yours looks very much like it's been growing in the dark... that makes these very weak and grow abnormally. Wintertime water is good for plants growing in warm, outdoor climates, but you need to be very careful about overwatering indoor plants- can easily rot them. It is normal to lose those very abnormal lower leaves, though. Perhaps the new leaves that are forming will be more normal sized and healthier (keep in as much light as possible without full sun (will burn in full sun at this point I suspect).

Ok I'll move this to a sunnier location and see what happens. Thank you!

I don't know if it's the right thing to do, but here's what I do with plants I suspect I've overwatered.

I put them in a warm place with bottom heat temporarily, like the stove top for a day or so. The pilot light is just enough gentle heat to dry out the potting medium.

It dries everything up and so far, all of the plants I've done this with have been none the worse for wear.

Good luck =)
