I'm being left out at church?

[cc]

Ok so at my church there are 6 or 7 girls my age and we used to hang out together but for the past few months they go everywhere but don't invite me.

It started with them going to the cinema without me, which was ok because I said I didn't want to see that movie anyway. Then they started going shopping and going to the park and cinema and didn't even invite me, now they are all best friends and don't even notice me. What makes it worse is that they always post about what a great time they had on facebook and list everyone's names, which just reminds me of the whole situation.

I've known one of them since we were babies, we were even christened on the same day, and the rest have joined the church in the past few years. I don't go to the church services but I go to all the youth groups. Then again so do most of them but some barely go to the church at all.

I just feel so left out but I hate confrontation so I'm waiting for one of them to just tell me they don't want me around. I hate feeling like I'm overreacting, does anyone have any advice on what I should do?

P.S I don't want to leave the church because I've been going there since I was born but sometimes I get really upset when they leave me out
I'm 14 btw
