From what I have gathered in the past, yes high humidity makes bacterial infections worse, that tap water needs to be dechlorinated. Whenever I did pedialyte soaks it was once a week with 5 ounces of spring water to 1/2 ounce of pedialyte, and that pedialyte needs to be unflavored. Force feeding should be a means of last resort if they haven't eaten in a few weeks, if she's eating there shouldn't be a reason to force feed, I would think. Hopefully she pulls through, I'm sure more experienced keepers can chime in soon. Good luck.
