Many stress symptoms can also be symptoms of physical illness. You need to know if you're dealing with a sick cat or a stressed cat (in some cases the former may cause the latter). Sometimes the cause of physical stress is simple to resolve, such as overgrown claws digging into her pads. Fleas bite the skin and irritate your cat;  what's worse, if ingested they can lead to a tapeworm parasite infection. If your cat is scratching frequently and persistently, perform a simple spot check. Buy a fine-tooth comb and run it through her fur around the base of the neck and tail: if you see small, brown shapes about the size of a pin-head, your cat has fleas. Also look for white or black spots between the teeth of the comb: these are flea eggs and dried blood excreted by the fleas, respectively. If you find fleas, you'll need to get rid of them on your cat, and in your home.  To eliminate fleas on your cat, consult your veterinarian for recommendations on a flea-control program that's right for her. At home, you'll need to take measures that include: rigorous vacuuming of all your cat's favorite places, rugs, and upholstery; washing your cat's bedding weekly; and possibly using a spray, fogger, or powder that is safe (follow product directions carefully and make sure the cat is not in the area if that is specified in the instructions).
