Please help family with school trip to Italy

Hello, my name is Carly! I’m a 15 year old high school athlete. I volunteer around my community and participate in summer college programs. My school is having a class trip to Italy, that my family needs help with. My mom is trying her best to keep up with our house expenses alone while taking care of me and my autistic little sister by herself. She works 2 jobs, and takes a few college classes online when she has the money to pay for them. She is doing everything in her power to put our family in a better position, she even tried starting a business. Personally, I feel that even with all of her efforts she still doesn't get paid enough and she's tired a lot. My mom and I work together to take care of my little sister so she can work more, but frequently has to take off of work anyway so that I don’t have to give up any of my extra curricular activities. My mother says this trip will help me experience the world more and educate me on different cultures so that I can become a more well rounded individual. I hope you can help us, anything is greatly appreciated.

God bless.
