Stressed about changes to New Years

So New Years Eve is in two days and today I found out we’re having guests for New Years. My brother and his new partner wants to visit us that day…we don’t have guests for New Years. For years it’s just been me, my parents and grandparents. And that’s what I’m used to and prefer. I can handle changes if I’m informed plenty of time in advance (though I had three weeks to prepare for potential guests for Christmas Eve and was still stressed, they didn’t come after all, I was relived to say the least)

I tried to keep my mask as well as I could but I could feel the panic rising inside me. And when I was finally alone I had a good cry. I don’t mind changes if I have enough time to mentally prepare but 2 days is not enough time for me. I already don’t like New Years as I don’t like being forced to socialize for hours and now we’re having guests? Safe to say I’m stressed out and very nervous.
