I've lost my friend because our two daughters fell out

I'm having a horrible time right now and hope you can help. A couple of months ago my teenage daughter fell out with her best mate over a boy, and this girl happens to be the daughter of one of my friends.

It all kicked off big time my so-called friend was badmouthing my daughter to all our other friends and there was some nasty stuff on social media, too. However, I didn't have time to deal with it.

As well as being a single parent, a relative died the same week this drama exploded, so I was taken up with that and deep in grief.

Our daughters are still not talking and my friend hasn't replied to any of my messages, asking to meet and talk. It seems very immature.

The worst thing about it is that I met the other women in our friendship group through her, so I feel like I have no friends now.
