Well, it depends on what you mean by 'need money' for your girls. If you're struggling to put food on the table and keep your electricity on, then yeah, you may need to explore some employment options. But if you feel you need money to pay for their iphones or new clothes or other things they can really do without until you have a nursing job or things they can get jobs and pay for themselves, then maybe it's necessary to have a family chat about sacrifice. We had to have a similar talk with my teenaged sons when I started nursing school
in August to let them know that we would not be going out to eat or to the movies and that Christmas would be lean. My oldest son got a job bussing tables and so when he wants something, he has to pay for it himself. Since money is tight, he even pays for his own haircuts and school lunches.
I know it's rough. There are just a few people in our class who work, just part time, and they are the ones who are struggling the worst. I hope it works out for you.
