Literally My Last Resort

I'm in a financial bind and want to resolve a debt by January 31, 2018. Last year I worked as a live-in caregiver for a family friend on a "promise to pay" situation as the individual was awaiting a settlenlment. I worked for this person about four months, no pay- not even gas money as I ran various personal errands for the individuaI. Towards the end of my employment, as I was awaiting compensation for my diligence, time and effort, my car was repossessed. Once my employer was notified (due to the fact I couldn't complete a task for her), rather than paying me for all the work I did, this person loaned me the money to get my car back. Up until that moment I had recently only received $700 for roughly 4 months of work. And the individual was able to loan me this money because they had received their expected settlement but still didnt pay me for all the work I did or indicate if they intended to pay me beyond the $700 I had received. I'm aware of how crazy this situation is and I've even been advised not to repay the person as they technically owe me. However I gave my word to repay them and had the intention doing so and never speaking to or seeing them again and count it as a loss and learning experience. I don't want to sue, I don't want to withhold my repayment- I just want it to be over. Unlike this individual, I am not irrational, nor unreasonable and value my word. I did have every intention to repay the money but as luck would have it, I lost out on another income stream which prevented me from repaying this personal loan. Please, if you can even just give $1 it will help. I'm single, educated, no kids, no financial support from anyone at all, not even my family. I currently work 2 part-time jobs that equate to less than 2 weeks of work per month and I'm still looking. I believed that working for that family friend was going to be the financial breakthrough to help improve the trajectory of my finances but it's proven to be a detriment and burden. Thank you to all that have donated, thank you to all that empathize, and thank you to all that share. God Bless and I pray it is returned to you tenfold. Amen.
