<human>: Let me start off by saying that I work in the finance/insurance industry and my long time customer came in this morning after not coming in for months and months. He was obviously distraught and asked if he could sit and wait until the store opened. Of course I obliged, and when we were exchanging pleasantries he broke down and told me that he hadn't been feeling well so he went to his regular doctor who referred him to a pulmonary specialist who had given him 8 months to live. He was very visibly upset (understandably) so I tried to comfort him without prying too much, but I did get a chance to ask what had happened and he said the specialist told him there was some issue with all of the scar tissue on his lungs (apparently it occurred during war and he received a purple heart). 

Since the store still hadn't opened yet, we were still talking and he started to lose his composure telling me that  his family had agreed to help him out but not a single one of them would let him stay with them for a week, he said that just this morning his wife told him that she no longer loves him and will not be there to take care of him or offer him any support whatsoever,  his siblings had abandoned him although he took care of them when their father passed away when they were all around 9 yrs old, so basically just a giant clusterfuck and a prime example of Murphy's Law and people just being dicks. I know it's completely inappropriate Of me to offer to let him to stay with me (nor do I have the space or desire to share my space if I did have it) and I don't have the funds to put him up in a hotel for a week. I have offered to help him out with grocery shopping (which may have been pushing a boundary already) but I really feel for this guy and don't know what else I can or should do.

Can you give me the gist of the text in a nutshell?
<bot>: Long time customer has 8 months to live, his family has abandoned him and I feel like I should do something but I don't know how or what.
