It seems fine to me but hey, what do I know? Sorry, I don't have any advice for you. I hope you find help soon!

It looks fine to me. The bottom leaves point down, that's normal. Do you open those blinds during the day? Is there some kind of white stuff in the crown of the leaves or is that just a trick of the camera?

You can see the tops of one in the bottom right in this pic.

looks thick and bushy, maybe the plant just naturally wants to drop some of the older leaves?

It looks perfectly normal for D. marginata, assuming that is what it is?

Yes, it is D. marginata - the original plant of this discussion. The one in my pic is D. marginata 'Tricolor.' HTH!

Edited to clarify ambiguousness

I am on my second indoor Marginata currently. The first fell prey to an awful case of what I believe is known as powdery mildew. If left unchecked it causes leaves to first droop and then drop. It also affects my current plant, but I have been successful keeping it in check with semi-regular applications of a neem oil based spray.

It's hard to tell from your picture, but look for a powdery substance at the juncture of the trunk and leaves.

For what its worth, mine has much longer leaves than yours, and many of them end up pointing downwards (drooping, I guess), especially as they get longer and older.

I don't know if powdery mildew is known to attack these particular plants, or if its because they both came from the same Lowes store.
