Germany Trip to see Dad

Hello, my name is Hanna, I am 16 and my family (younger brother Anton, and little sister Ella, as well as other family members) and I need funds to go visit our father who lives in Germany for Christmas. Any amount at all would be very helpful. Since our grandmother (legal guardian) is retired and our father is sick and has been diagnosed with ALS and no longer has the ability to work, we are tight on funds and need some help. It is very important to us to be able to see him, and we would be very appreciative and grateful for any donations received. Thank you.
