Help Me Help My Sister Help Herself

My sister is going to be so mad at me for making this public plea on her behalf but I have exhausted all my other avenues and then I was listening to "Christmas Shoes" on the radio this morning and broke down and cried and it got me thinking others may want to help us out! This song hit home because my sister was just diagnosed with lung cancer in October and has been receiving treatments since.  She has a 13 year old son at home and her older son just gave her, her first grandchild this year and this Christmas is most likely going to be the only Christmas that she will ever have with her grandchild and the last one with her sons.  It hurts me to see her hurting!  She is trying to be strong for her family and I have told her many times that we are here to be strong for her not the other way around, but that is just her way!  She is the most caring, giving, loving, honest person you will ever meet!  She gives and gives and gives to others expecting nothing in exchange!  I do not know God's plan for us all - but sometimes I question why he takes the good ones!  Her fiancé has had to take a lot of time off from work in order to be with her and take her to her treatments which has caused  extreme financial difficulties for them and they are behind in ALL of their bills.  Not to mention co-pays and expenses to get her to and from her treatments which they incur everyday.  Their wedding that was supposed to be next summer has HAD to be moved up to December 22, 2018, my sister wanted a summer wedding not a winter wedding but she wants to marry her fiancé with whom she has been with for the last 13 years and whom has stood by her and taken care of her during this extremely difficult time without complaint and I also think she needs something to take her mind off from her current situation.  My family and I have been trying to throw this wedding together as quickly as we can and I have maxed out all my credit cards in doing so but there is so much still left to do and pay for before then.  We still need a DJ, if anyone knows anyone!   I implore anyone that can help me, help my sister, help herself, to donate whatever they can!
