Most Helpful Guy
There are a lot of other jobs besides waiting tables, and a lot of them pay better. You'll need to find room mates to split the rent most likely. Also, if you're moved out and not living at home, it will be easier for you to get financial aid for school. You'll have to live lean until you get through your nursing program, but that's a worthwhile investment since nursing pays so well. Whatever you pick as a first job will most likely pay crap, but if you bust your ass, learn your job inside out, and keep focused, you should pretty easily be able to get promotions. Most people your age are too concerned about partying and having a good time to give you much competition at work, and the kinds of jobs most people get with no experience have high turnover, so there are always opportunities opening up.
And there's absolutely no shame selling your eggs as long as its not black market. There are people who desperately want to start families, but are unable to do so on their own.
