I cancelled dinner

I didn't wake up properly today. I only had around 3 hours of sleep. My dad called me to say we'll have dinner with my uncle. I said, maybe we can have it at 16:00. Around 14:30, I went to the mall to get my hair done. The line in the salon was long. I waited around 30 minutes before moving to another one. My dad was calling me asking where I am so he can pick me up. I said, he doesn't have to. I also asked if it was possible to move the dinner to 5 because the cut got delayed. He said no, I said, how about 16:30? He agreed. By 16:20, he was calling. Asking where I was so he'd pick me up. I said it was not necessary. They can go ahead to the restaurant and order, I'm just running late. 10 minutes later, he messaged me to say my uncle had already gone home because I was busy. I was livid because I've been trying to make it work despite the same-day invite, and suddenly, it was my fault it did not push through. I'm exhausted and sleep-deprived. I just got married, and I'm about to leave…
