chin hates being held and touched

So my 16 week old chinchilla absolutely hates being held and touched!! I have has her since she was 10 weeks. She is used to her home and her new surroundings and even used to me, she comes up to the door when I walk in the room and she jumps on my hand and eats out of it. But all **** brakes loose when I reach for her, she squirms like crazy, kicks, bites and sprays. She let's me pet her sometimes for a short period but picking up is bad!! I don't try to pick her up or touch her every time I put my hand in there, so she knows I'm no in there to hurt her or annoy her, I let her come to me most of the time. Should I continue to hold her and pet her and eventually she'll get used to me?? Or what should I do??
