Thanks so much for all of your responses. There were tests done on her
stool and everything was apparently fine.

I think I'll be trying to find a vet with a more "holistic" approach. I
keep thinking that treating 1 symptoms is just going to make things
worse, and since all of these symptoms have developed over the last 2
months I would be inclined to think that at least some of them might be
related.

I don't know if she was checked for cryptosporidium or giardia - I'll
look in to that.

Thanks again everyone!
