6cc of pepto to stop diarrhea and electrolytes. If you don't have access to electrolytes right away then drench her with gatorade or pedialyte. Pick some leaves off a tree and she should eat them since those are a favorite snack. I would get a fecal sample into the vet ASAP, sounds to me like Cocci. Inject her with Iron 100 to help with Anemia which can cause the weakness.
