Help me pay off my student loan debt

Hello,  I graduated from university with a degree in biology in December of 2013. I spent most of my college career alternating between working full-time and part-time, to pay for what my loans did not cover, and trying to survive. It was a long 4.5 years (including summer class), but I survived, and only came out slightly malnurished. 

Since graduating, I still don't have a full-time job. I do have part-time work that I do for my fiance's parents and in exchange, they cover our cost of living (way more than they should). I try to help out when and where I can, and that means I make several trips across the country to help them out, away from my friends and family.

My fiance' is still in school and will not graduate till May, so he is unable to provide any income. I want him to focus on school, so that he can graduate, since he let me have a year off while he worked and went to school. What I need is your help so that I can pay for my upcoming student loan payments. I have deferred them until December, but I'm unsure if I will be able to defer them anymore. I will have to pay $331 a month when they start back up.

I am always looking for a job in my field, and put in multiple applications a day. There are not that many jobs out there for just a BS in biology. Actually if there are any, I have yet to find them. To be honest, I have applied for jobs that are not in my field, but still no bites. I used to serve tables, but am unable to do that anymore. I was in a car accident earlier this year and hurt one of my arms. I still don't have full strength in that arms, and it tires easily. It seems I am running out of options left and right. 

I hope to one day go back to school to get my PH.D. but that won't be for a few years.  Any help would be greatly appreciated!
