Oh, I did not realize you are from Africa. And, it sounds like you have an extended family structure to boot. OK, I am going to change my advice a bit.
You REALLY need to tell your parents and other relatives that you borrowed so much to pay for your schooling that you are working 2 jobs to pay off the 5 loans you have and you just CANNOT afford to borrow more.
Then tell them you can only send them perhaps $50 a month because they are your parents, but that you really cannot send any money to other relatives at this time. For me, anyways, this would work.
I can hear some of the Mustashians hyperventilating at the idea, but in an extended family you not only receive support from your family you are also expected to give it.
I grew up in an extended family, and if somebody wanted to add a room to their house they would have 8 willing workers at a phone call, if somebody wanted to paint you would have a dozen teenagers as well as it was good for us to learn this stuff, if somebody was unemployed there were a dozen people calling in with ads they had seen for help wanted, etc. This helped us all lot in life, but just as you receive help you are expected to give it: EVERYBODY is more prosperous for it. And her family thinks she can do more than she can.
Everybody wants their family to know they are doing well and everybody brags a bit. But they think she is doing better than she is, and telling them that she has already taken out all of the loans she can get might help. And, with her income level, I suspect that a $10,000 loan is more than she could manage even if she could get it. And that is *IF* she can get it. Student loans are easy to get: other loans may not be.
Giving her parents a small amount of money every month might help: I do not know. I do not know enough of the situation. Bevn182 is obviously very bright: she would know better than I.
