How to send a text message apologizing for not being able to keep an appointment, using ancient languages

I am delighted and honored to hear your invitation. After years of separation, I shed tears every time I think about my classmates and old friends, and I wish I could never see each other again. However, everything in the world is subject to God's will and cannot be saved by human effort. When I want to happily go to the appointment, suddenly something else is urgent and it is difficult to escape. It feels like falling from the sky and my heart is burning, but I can't help but sigh. It's hard to go today, and I really owe you the kindness of the king. If he is lucky enough in the future, he will definitely rejoice with you. I apologize for any inconvenience.
