I need your advice

Hi, My name is Jenn and I am new to this site. I would like to get your opinion if you don't mind. I am 29 years old and turn 30 in Dec. I have my BS degree in HR Management and haven't been really happy. I always had a strong interest in healthcare and had done alot of research about careers and have narrowed it down to the following:
Master's in Healthcare Administration Entry Level Master's in Nursing Master's in Public Health

I have followed people in each career and love them equally. I just can't believe it. The programs would take 2-3 years to complete. Can you give any advice as to which career you beleive will be up and coming in the future? I worry about job security. My husband is from Europe and we will eventually move back there and I would like to know there are jobs for whatever I go back to school for. Pro's/Con's for the above jobs. I really appreciate your time for reading this and look forward to your posts.

Warm Regards, Jenn
