I'm 21 and my sister is 15.
Now we grew up in a very competitive environment with a lot of comparison between the two of us
Now the thing is we both shared a healthy relationship until she grows and now she's jealous of my everything...
My looks, my clothes, my boyfriend, my education all seem to hurt her a lot
Well she gets along fine with my mother and so she is trying to poison mummy against me...
What to do, I really love her a lot
