Volunteering in Israel and Palestine refugee aid between 16th of May 2016 and 13th June

Hi my names Rachel, currently living in Yorkshire, England. I have wanted to do a certain trip and volunteer experience to Israel and Palestine, ideally completing the Israel Trail which is a 628 mile trek across the entire country of Israel. Also due to the ongoing problems between Israel/Palestine, 1000s of Palestinian Children are denied access to basic education, security and rights, I would be spending a part of my trip in the West Bank volunteering with project hope which helps these children. My flights are booked and paid for and will be flying to Tel Aviv 16th May and returning to the UK 13th June 2016. Now i have to fund the rest of my trip for accommodation, travel inland, food, expenses etc, and suddenly find that I'm not able to get this amount before I fly. Please could you help me even as little you can as this will be a life changing experience for me and feel I've got a lot to offer to play even a tiny part in helping the people in crisis and to give back. Thankyou very much for taking your time to read this. Rachel
