Just say no
"Sorry, I don't feel like going, it's me day. And if you keep forcing me, I'd be a bitch and we don't want that."
She was my bff and I could tell her that without feeling guilty then you can say no
They are your friends, they should understand
Social anxiety can make that near impossible tho
Also, I had a friend who knew I didn't like going out, especially in groups, and usually I'd just say no or I was busy and one day I was studying for a really important test and told him that and then he lost it telling me I'd make time for him if we were really friends ( despite him declining offers to come over to my home to hang out)
