Can Anyone Help

[teena]

i have a nine year old Albino corn snake, who has just recently began circling her hide and jerking its way around in circles.

she has recently shed , but has not eaten for about two weeks, although food is placd in the vivarium.

i am unsure what the jerking is about, she looks healthy and has a good bright colour, shred came off in one place.

i am wondering if it is related to mating or something.
i would like to speak to others who may have experienced the same thing.

many thanks
