new to blogging

This is my first time blogging and I'm not sure how it even works. The only thing I know about it is what I saw from the tv show, House. So I am a college student, single mother of three girls, currently unemployed but seeking work. Hence why I'm going to school because getting a good job in this town is close to impossible! So, I guess, I need to do some research on this whole blogging thing so I know what I am doing! lol
