Wanting to return to university, but I have a Master's degree. Funding options? My undergraduate is in Biology, I'm a US native.  

I'm thinking about going back to school to study a more quantitative discipline like statistics or computer science.  

Does anyone know of any scholarship websites, fellowships, or other ways to pay for school expenses?

Right now I'm looking at taking out more loans.  If I work for the government, I'll qualify for their "Public Servant Loan Forgiveness" program which will help.

If anyone has been in my position please let me know how you managed to retrain while not owing your soul to Sallie Mae.  Already having a graduate degree really hurts when it comes to finding financial aid.

Thanks in advance!
The only thing I can add to jakebeal's answer is that, it is generally only true for STEM research masters. Most coursework degrees, even in STEM, are not funded. It was unclear from your question whether you were thinking about doing a second masters with a research component, or just looking to get a coursework masters. 

That said, if you are looking for a research masters, I agree with jakebeal. However, I don't know of any school or organization that will fund a coursework masters.
