100K in loans is NOT worth it. If I were you, I would keep working at the $40K/yr job (or find a similar one that you don't hate), pay off your student loans, save up a little money, and then go to a community college and get your associates degree in nursing. Apply for scholarships
, as many as you can. If you aren't able to work, you may have to take out a very small loan for living expenses, but it should be nothing close to 100K. You can then start working as a nurse, gain experience, make money, and get your employer to help pay for your RN-BSN.
Remember, 100K is just the loan, you will have to pay that back PLUS INTEREST.
Don't do it.
