Women in the workplace

I am wondering if there are any women on here in a male dominated field? If so what is your profession? And how do you find the confidence/drive to stick with it when your against all odds and not to mention the men around you either make you feel like a sex object or that your only place is the kitchen.... I'm am going to school to be a diesel mechanic and I'm just finishing up my freshmen year... I love it but the people around me make it very hard to want to be there.
