Upset

I am so upset, I am in this church group and I overheard one of the girls talking to another about her birthday party she had. So I asked what she did and who was there and she said just my friends from church and whoever was invited.Umm I go to this church and am in this church group am I not your friend? So I asked like who specifically and she listed pretty much everyone in my church group. When I asked was so andso from church there and so and so her friend that mentioned it said it was just her friends and who she invited!! Omg I was just trying to figure out who else from church was there
