Was I harsh when I denied him money?

My dad asked me to lend him 10 000usd. He’s building a house. This sunmer we went holiday together and I paid both of our plane tickets (he said he’s credit card is not working and he will pay me later). Still I haven’t got 850usd back that he promised to pay me back. I do understand things got in the way (our grandpa died and now he’s started to build this house)

10 000 is a lot of money and is half of all of my savings. I’ve grown up in very dusfubctional family and learn from very little that I have to be independent and not seek help from others.

this causing me a lot of anxiety because I might not get my money back or it will take long time. This year so far I’ve already lend 1600usd to my family (my dad and my siblings)
