<prompt> Human: Hello everybody, its been a bit overwhelming this past week so I apologize for not being as concise as I can. Here is the situation:My mother has raised us up by herself after the divorce about a decade ago. There are 4 kids - Im the oldest 1st year in dental school, busy in the semester but I have the break now to plan everything out, a sister is in another country learning a language after getting her bachelors in fashion, a brother in the army in AIT, not much flexibility on his end, and the youngest sibling 15yo, freshman in high school. My dad lives in the same town, so there is an option to have my youngest sibling to live with him to remain in her same class. She doesnt like his new wife, but that might be the best option.If the treatment doesnt go according to plan, she has about 1-5 weeks to live.I dont know how to handle finances or anything because my mom would do everything. I dont know what to expect when she passes away and what is the best way to go about this effectively, efficiently, and with the least amount of pain. I honestly dont know what to ask you guys because Im figuring things out still. I just know that I want the best for my youngest because shes the brightest out of all of us and have a lot of potential. She really looked up to my mom as a strong role model. Any help would be appreciated, whether it be financial or just general advice. Edit: Thank you everybody for your responses. I know its just text over the internet, but it really helped me to regain focus and not feel as alone as I was in all of this. I have read all the comments currently, but I dont have time to respond. Ill respond as much as I can when time becomes more free  <response>: First and foremost, get her to do a will. Last year my mom passed and didnt do a will. And its just a pain in the ass to get things situated. Sorry to hear you are going thru this. I stayed with my mom majority of her last few months and it was by far the most mentally exhausting thing i have ever done. Good luck to you and your sister
