How do you stop explaining yourself to people

I'm just so annoyed

I've become extremely antisocial

Am I the worst person for being so annoyed with everyone that tries to be my friend?!

I really don't want the pressure of having to explain myself to everyone everytime I don't want to hang out! I am married and have 3 kids ages 6 and under, I do not have time! I do not want to hang out on my "free time" I don't have any free time! I want to clean my house by myself all day long and hang put with my family only!

I don't want to hang out with other people + my kids, they distract me from taking care of kids when they talk too much 🙃

Why is that so hard for everyone to understand?

Am I wrong?

How do you deal with this?

What triggered me right now is that I have a neighbor that is pregnant she's due in January, I told her I have a brand new breast pump she can have and I was going to take it to her on Thursday when I had time but I was too busy by the time she got back to me so today she said she was going to come and to let her know what time

I don't want her to come to my house, I am stressed enough trying to clean and keep the house clean since my kids are home from school for the weekend and they make a huge mess so quick 🙃

Also I don't want them getting all riled up and the dog all wild of someone comes over and if I got outside to give it to her i already know everyone will go outside with me and it's too hot to play outside and they are just going to throw a fit if I don't let them play outside and with my luck the other kid neighbors would go outside to play with the kids and I just don't feel like being outside in 100 degree weather

So I told her I'll drop it off another day and she said "are you sure?" "Is everything ok?"

🙃

Why am I so annoyed at this?
