When I was at the same school I was getting bullied by this girl called Zena. She was a dickhead. She basically did the same thing that Desiree did. But she didn't swear at me or call me names. She took my friend away from me. Well what she did was not even that bad so it wasn't as bad as Desiree's was.
What she did was she would convince Erica that I didn't want to be her friend anymore but in fact I did and she bribed her with all these things that Erica basically just went to Zena and ignored everything I had to say.
Let's just say that I told Erica mum and her mum spoke to my mum and they fixed things up.
How I solved this was I spoke to my mum and then my mum spoke to Erica's mum and that is how I solved it.
Well I really can't give any advice on this situation as it wasn't that bad. But what I can say is that maybe don't let that rood or stupid friend take ur friends away from you maybe tell someone if it happening
