help me visit my long lost family

Ok this is going to sound completely made up but I promise you its real. Back in september last year I found my dad after never meeting him ever. Im 27 about to turn 28 and I had never flown. He lives in Australia and when I found him I was so happy. I have 3 sisters and my nan and grandad out there. So I scrimped and scraped and managed to get my passport and flights to meet them. It was the most amazing time of my life to be with them but as I work I could only be there for 10 days. When I came back I had typical bills, christmas, birthdays etc. Now I am due to fly back in the middle of may to whitness the birth of my nephew and I really cant afford it. Im doing all I can but if anyone can help it would be so amazing. Thank you for at least taking the time to read this xoxo
