Aita for borrowing money and saying they’re overstepping and entitled?

So I borrowed money from a family member two weeks ago I told them when I’d pay them in two weeks. Recently my cats health has gone down where I’ve had to take a few days off they are still going to get paid from the date I said. So because I’ve been off there assuming they’re not going to get paid. It’s only 300 dollars I make that in a day. I have not paid yet due to his vet bills which should be covered by his pet insurance. I took another day off today to make sure he is okay. Sent them a text and immediately asked if I was off and why wasn’t I working. Then demanded to know why. I then explained when they agreed to get paid id still pay them on time and they feel entitled to my work schedule and I shouldn’t be taking time off work. Mind you I work 100 hours every week except this week due to my cats condition to nurse him back to health. I said that they are being entitled and rude. The money was used for bills so I wouldn’t be late they will be getting paid in two weeks upon the agreed arrangement I then explained that what I do in my free time is none of their business am I the asshole? The amount is $300.00 which I will have that following week.
