God invented taxicabs for a reason.
Honey, if you cannot learn to say no to a whiny friend who is (nominally) an adult and (presumably) can handle the rejection of a negative answer, how will you deal with a fussy 2-year-old who wants chocolate, or doesn't want to go to bed, or demands a toy at the store? If you think your friend won't take no for an answer, the willfulness of toddlers and children will knock you off your blocks.
Make your mouth form this word. "N o." Then ask her to please stop asking you. You don't have to defend any of it with distances, gas prices, waiting in the car when swollen, or anything. You can say no even if the place is next door and you are feeling fine. You don't want to do it, and that is all you need as justification.
Take care.
