In all honesty, you have nothing to worry about. As mentioned, it really is a matter of time, as long as you cater for its basic needs (food, water, the occasional cuddle). In the long term she'll love you for sure, but in the short term you need to make sure you do not make any sudden movements. Sudden movements scare kittens, so if you're going to approach it, ensure you move really slowly and be extremely gentle. Millshre makes a good point too; sometimes you can try too hard to be affectionate, when the cat really needs space as much as you do. So in general just remember there's no rush, just let the cat grow to like you, because she will I guarantee it.
