Am I overreacting ?

I’m in currently taking classes for college over the summer, and I live pretty far from the community college (I live in the country). My friends always want to do something and for some reason my friend always asks me to drive even though she has her own car. Idk why but it’s been irritating me because I have to drive all the way into town for school and then work, and then all the way back. I have to refill my tank every 3 days. Am I overreacting ?
