Hi there!
First of all, congrats on your new ferret, though it wasn't under the best of terms.
If she is gaining weight and eating, currently, you're probably OK in terms of depression. If she were still looking scraggly and not eating, then I'd be concerned.
But...I personally don't think having 2 is much more work than having one, particularly if you have a cage that can accomodate 2 ferrets. You've got twice the poop and twice the vet bills. The vet bills certainly aren't cheap for ferrets, as they tend to develop cancers later in life... It certainly is fun watching them play together, though.
Give it a little time and see if you end up really wanting a second ferret, though, would be my advice....
