Serenity's Washington DC Alive Trip

Someone important in my life made me a promise & unfortunately broke that promise. I have been very heartbroken and disappointed from the news. So now I'm asking for donations/financial help at the last moment. I have been looking forward to being able to go in May on the Washington DC Alive Trip with my 8th grade class all year! To my disappointment the only pmt that has been made towards the $1500 is the $99 non refundable fee to save my spot. IF my mom & I would have known pmts weren't being made, as we were told, then my mom would of been making these pmts all school year long! But now I'm asking for all of your help because going on this trip means the world to me and it will be a once in a life time trip. I have until April 17th to come up with the final pmt. Trust me I know times are tough financially for everyone but any little bit of help is GREATLY APPRECIATED!!! So PLEASE if you're able too or know of others kind enough to help me be able to go on this amazing trip, I will be forever extremely gratefull!!!
