At 13 weeks old, she's just a baby.

I'm really sorry this is stressing you out so much, and while you're used to more socialized kitties, because you're committed to this little one (and honestly, you don't need to worry about getting her spayed for another few months. Of course she CAN be spayed earlier, but it isn't necessary), think of it the way we do.
Imagine you're a very young child. You've just lost your entire family. You are put on a plane, and flown to China. A family picks you up and brings you home. Everything looks different. Everything smells different. You don't understand what's happening or why. You are scared out of your wits. You're given your own room.
Do you want your new mom constantly hugging you, brushing your hair, loving all over you?
Or do you want to be left alone, given time to adjust?
If they feed you food you like regularly, if they clean up after you, if they make sure you stay hydrated - and leave you little toys, or play a game with you if you show interest - isn't that more comfortable for you?
And if your new mom sits in there and reads out loud, not forcing interaction - and you can just watch her and listen to her - and when she leaves, she leaves a yummy treat behind for you.... don't you start feeling more comfortable? If she lies down on a blanket on the floor and takes a nap - so you can see her, just sleeping - totally non-threatening - down at your height - doesn't that help you become more comfortable with her?
Some kids will be fine right away. Some will take weeks. Others may take a few months.
If your new mom is completely freaked out that you don't love her immediately, and all you get from her is stress vibes - doesn't that make it even more difficult for you?

Take a deep breath. Take a lot of them.
Before you go in her room, sit down. Close your eyes. Concentrate on breathing deeply and slowly. Imagine releasing your stress, your fear, your concern. Watch it "wash" away from you like the tide going out. Slow down your heart rate.
Then take your favorite book, enter the room, and sit down and start reading out loud.
Get a t-shirt good and sweaty. When you leave the room leave a yummy treat down for her on it.
Please just keep working on turning off the clock.
