Funny, as a fluffier gal I have no problems with wind. Hills, yes gravity is my enemy but wind, my leg strength and size is helpful. It is good, if riding with others, to draft. Unfortunately people usually like to ride behind me in a headwind (wonder why) and won't help me out!

The key is to get stronger. Larger people actually do better in wind than the smaller guys who get blown around (I saw a whole group of lightweights blown right over once. They were knocked down like dominos!).
