Feeling terrible

My daughter is 3. About an hour before bed she asked me to have a tea party with her. I told her no I want to be left alone. My husband wasn’t feeling well today so he was sleeping all day so I was taking care of the kids and they had so much energy and we couldnt go outside or anything so today was just exhausting. I was tired and over it. I honestly really did want to be left alone. I told her we would have a tea party tomorrow. She looked so sad. I’ve been feeling terrible about it all night ☹️ I really didn’t say it that nice either.
