Advice on my friendship?

Well I know I’ve posted quite a few q’s about this, but right now I don’t know what to do. I’ve read everyones advice but they’re not listening.

They completely ignored me at diner today and were obviously talking about me. You know when your walking over to someone and theyre looking at you and laughing, then when your like ‘hey, what you talking about?’ they just reply ‘oh nothing’.

It’s upsetting me so much that they’re leaving me out. It’s also annoying that they act totally different if I’m the only one there. They’ll talk to me like nothing ever happened and both of them always go off with eachother.

The other day when I was going to line up for tutor they practically SPRINTED away from me. I was going to try and catch up but I just thought ‘what the f*ck is the point?’ and walked to the yard. Then when I got their they lied and said ‘sorry, I had to go hand something to a teacher’, eventhough I KNOW they didn’t, because I watched them run outside.

They constantly mock me and are like ‘you hair looks so frizzy!’ just because I don’t straighten it for school (because theres no point as we have to tie it back), or ‘I can’t get past you, you fat lass’

It’s knocked my confidence so much and they do it deliberately.

It’s not only me they do it too either. Another girl hangs round with us, we’re generally like a foursome. But one of them is ALWAYS horrible to her when I’m there. She complains about how annoying she is and how she hates her, but then when shes the only one there…well, you can guess this, but she’ll be like…her best friend. She always runs away from her aswell and I feel so mean for her, because when they do it to me it makes me feel so awful, so it must make her feel bad too. I don’t understand that girl most (the one that complains how she hates my other friend. She’s the one that ditched me to go out shopping with someone else). She can be such a b\tch, then at other times, shes nice.

Sorry for repeating myself, but I need advice on what to do now, and I just needed to get it off my chest.

(also, sorry if this is so long)
