Aww, how sweet...I just want to hug that little kitty.
We found Tinkerbell, our first kitten, abandoned at two weeks old by her mom, covered in fleas. We took her and took care of her, knowing NOTHING about cats. She wasn't special needs but she was a special situation in our case...and we have such a close bond with her. I bond with all my cats...but she'll always be our amazing little angel.
I would love to foster, but I have no time at this point. I think I would get too attached, too...I'd be worried about not being able to give he/she up when I was done. When I'm in a more stable situation I have definitely thought about looking into it...so I'm interested to hear how your experiences go if you decide to do it.
