Not all foster cases go like that. I had an entire summer like that last year -- which is why I'm not fostering this summer (that and Pouncer got so stressed from all the diarrhea last year that he now stresses over everything)

Have faith things do get better. Its amazing to see them finally get healthy and find loving homes of their own. My sweet Agnel (who oozed poop from her butt every time I picked her up) landed in the BEST home and I get updates all the time from them. It IS worth it and there are some smooth fosters, some with bumnpy roads. All leave indelible marks on your heart.
