Skittish rabbits are usually that way because they have not been handled much, or have not been handled properly. But being able to handle and carry them is important- it makes rabbit ownership more enjoyable to be able to spend time with your pet, and it is necessary for regular health checkups.
If you have a smaller cage available, I'd recommend bringing the rabbit inside your house (or garage, somewhere protected) for a few months. Make a point of touching the rabbit daily. It is more threatening to reach around and pet the body than it is to touch the head/ears. So I usually spend a week or so just tempting nervous rabbits to me with a treat. Once they're comfortable with eating from your hand, you can start slowly reaching up and scratching their forehead while they nibble on the treat.
There is no smooth transition from that to picking up/carrying, so it's something you just have to commit to and carry through. Most rabbits will want to back into a corner before you pick them up, and that is okay. Let her back up, then reach in and lift her belly with one hand and rump with the other. Hold her firmly and lift her quickly to your chest. From there, I usually walk around for 5-10 minutes scratching their head while carrying them.
Do this often, daily if possible, for a few weeks and things should turn around. I handle babies from birth, so they often grow up used to handling and attention, but I'll occasionally purchase a rabbit that has not been handled much and is fearful or nervous. Those are the steps I take with them. Bucks are very, very easy to overcome and often turn a complete 180 into attention-seekers. Does are a little more difficult and still may only "tolerate" it, even after a lot of work. But that's good enough and will allow you to handle your rabbit when necessary, or just for fun, without problems.
