Aw I'm sorry!!

any pictures? Is it hard bloat or soft bloat?
Soft bloat it looks like a partially filled water balloon under the skin - very wiggly and jiggly. Comes on suddenly.
Hard bloat looks like a balloon being inflated with air - very smooth and puffy. Usually is more of a gradual puffing up.

I have a feeling you have soft bloat, which is similar to dropsy judging by how suddenly it has developed and that she is floating frequently. (often caused by a bacterial infection which may or may not be linked to you being busier...)

Treat with Maracyn II or Maracyn plus, I would not used expired medications as the potency may no longer be accurate.
I'd continue with the salt baths. I'd try increasing her bath time to up to an hour, even do two 30 minute baths if that is easier for you.

Unfortunately not all cases of soft bloat are curable. Is Ruby your only frog? If not I would separate her from the others as if it is due to a bacterial infection it may be contagious.
