A little gross question... I'm worried?

Yeah, bronchitis and pneumonia sounds about right for your symptoms. Just be patient, follow your treatment plan (drugs, re-hydration, etc.) and you'll get better. You shouldn't dehydrate if you are using those Popsicles. You'll probably gain the weight back as fat but you're losing it as fat right now so you won't be any worse off. (I lost 10 pounds in three days of being lost in the wilderness and got most of it back fairly quickly after my rescue.)
