I need advice!

I need some advice. I currently work at a job that has nothing to do with education at all (education is my major) I make $16 an hour, around 36 hours a week. I work 8-6 M-Th. I have an interview this week at a school as a para who makes most likely $14 an hour, better hours, and will most likely lead to jobs within the district once I graduate (next summer). This district also has a paid daycare for my son to go to, they will help pay for school, as well as pay for my alt. Cert. once I graduate. This seems like a no brainer. But I feel so guilty for leaving my job without a 2 week notice since school is starting back in like a week and a half. What would yall do in my situation?
