I'm so very sorry to hear of your loss of sweet Gidget. Sometimes baby kittens are already sick and it just hits them so quickly before you have a chance to even notice.

I don't know about your shelter, but ours will allow you to adopt another kitty if it's only been a short time and the first one passes away. Maybe you could save another life from the shelter? Good luck, and I hope the pain of Gidget's passing soon ends. Please know that you showed her love and gave her a chance at a wonderful life ... there was nothing more you could have done for her.
