Listen to your mother! Two years is a LONNNGGG time to be miserable!
One factor to consider -- if circumstances mean that you will end up repaying the scholarship, will it have to be repaid in a lump sum?
(If, for example, you meet and marry Mr. Right and move to another state).
Do your research-- talk to some of the nurses who work at the hospital. Your school might be able to refer you to their graduates who now work for the hospital. Talking to nurses who are now working for the hospital on the scholarship repayment program you are considering would help to make your decision easier.
Talk to the admissions advisor and someone in financial aid at your school - there may be other scholarships, etc. that you are not aware of. The Federal government has a loan repayment program for nurses that requires you to work in any one of a number of facilities in "healthcare shortage" area - and you are not obligated to any specific facility.
Basically, consider all of your options carefully and do what is best for you.
Good luck in school!
