<human>: I'm a 23 year old female. My friend invited me to go to Ocean City Maryland with her family for college week. The cost of the trip is $86, and I need to pay her aunt back. Her aunt and I both live in Virginia, roughly about half an hour apart, while my friend and her family live in New Jersey. I've owed the money for about a month or two now, but any time I'm in the general town that my friends aunt lives (and/or I have the money) I ask my friend for her address to drop off the cash. Each time my friend hasn't given me the address, with either replies of "I don't know" or no response. 

This week is Electric Daisy Carnival, and after the $140 ticket, I spent most of my paycheck on making an outfit and makeup. The festival is tomorrow. Last night, my friend told me to bring the money owed so she can mail it to her aunt. I really wanted to be able to buy things at the festival, but with all the money I've been dropping, and the the cost of tolls and gas to get up to Jersey, I don't think I'd be able to do purchase much of anything besides food if I gave her the cash.
I asked her why she wouldn't just give me the address, and she said its because she doesn't know it, and that her aunt was staying with her boyfriend but they are fighting. I feel like if I had gotten more advanced notice on her wanting the money I wouldn't have spent so much on other stuff, (including a $75 gift for the same friend because I missed her birthday) but now I'm super bummed. Would it be terrible to tell my friend that I can't afford to give her the $$ because I want to buy shit at the festival? 
Also, please don't get uppity on how I spend my money, I always pay my bills on time and have near excellent credit.

Can you condense the text into three sentences or less?
<bot>: I owe my friend's aunt money, and have tried to pay it back several times, but now said friend wants it at a really inconvenient time for me.
