How long have you had your cat?
If you have only had her for a very short period, there is nothing to worry about. Just do your usual things, feed her, give her water, provide her with toys, etc. Let her know you are doing these things for her well being. She will eventually get it if not right away. Giving her a little treat when she is hungry might also do the trick.
Personally, even when I am a total stranger to the cats, most of them will become warm toward me quickly when I pet them gently. You should also give it a try. Don't try to hold your cat by force when she doesn't want to, it will only alienate her. Use treats to lure her to you, then pet her. She will start to like you.
