Help elderly parents due to the untimely loss of young son.

Last week I got a call from elderly parents that my baby brother is sick and in hospital. I kept calling every few.minutes for updates and was later told he has meningococcal sceptecimeia. At 1145pm I got a call from dad that elshin is no more. This was such a shock as elshin was such a healthy person. I went to fiji for the funeral. Now I am worried about my parents as they are devastated after his loss and no one to look after them. I am trying to get them over to nz and this will incur a lot of expenses as my wife.doeant work and looks after kids. I had taken a huge loan which has been used up in travel and funeral expenses.
