I'll also throw my approval of Richard's and Taga's comments. If you have been employed, where is the savings history from the 34K a year you make? Most financial books or advise will tell you to save 3 months of salary into a slush fund for "emergency use" which you are definitely experiencing.
Credit, just like a drivers license, is a privilege not something we deserve. If you can be responsible and be safe like everyone else out there, you can keep your privilege and not loose it. If you loose it, you need to do your best in earning it back as quickly as possible. If you need to lean upon it from time to time or depend on it, then it shouldn't have been taken for granted.
My only advice is that if it is truely a Family Emergency, and your family is in need of you for the emergency, that same family will have to help you out financially to get you there. Lay down the pride, and let them know that it's only a financial thing that stops you from your attendance.
