Does it sound reasonable that I want some time alone?

I just came back from holiday and have a sinus infection and also jet leg. I feel exhausted as my flight was cancelled so I was stuck for a day so when I got home only had a day to sort everything out before going back to work. I didn’t get in until very late at night and had minimal sleep. Yesterday was the only day I had to sort things out.

Relatives came over during dinner yesterday and the kids were shouting and screaming the whole time, hitting their mum and behaving really badly. Today, I’ve been really busy and more family are here. They still haven’t had dinner yet and it’s past 9pm. I feel like I’m constantly in the spot light and have 0 privacy. They were questioning why I didn’t want to have dinner etc. and I’m simply not hungry and feeling great. I find it annoying when people question you because you don’t want to do what they do. I don’t meant come off as negative, I just like alone time sometimes, and I get very overwhelmed around a lot of noise/people. Does it sound fair that I just want some quiet?
