HELP ME GET TO THE UK

Okay so getting the money to finance my trip to the UK (which is required for my International Studies major) in January 2016 has been more difficult than anticipated and with my mom being medically retired and having to deal with her own significant medical issues, bills, and helping me get ready for the next semester, there's nothing left to contribute to the $5500 trip (of which the school only covered $2200) and I just want to ease the pressure off of her as much as possible, however my miniscule paycheck barely covers anything and I can't secure a loan from the bank by October 1st when the money is due. At this point, she's being driven to sell her jewelry and prized posessions and I don't want to force her to do that. Every cent helps, so please if you can~ Thank you so much!
