This is a tough this your family is going through. My brother lost his daughter due to lukemia and it was especially hard on them and I felt that pain because I live in Florida and they live in Michigan. I wasn't able to be there for him and it was tearing me up. Distance can be super hard when you want to be close to those that need you.
Keep your faith and a positive outlook....... you have your goal to achieve and you now have a little angel watching over you. Time will heal the pain and determination will help you reach your goals.
