What do you think of me tearing my sister's new dress because I was jealous?
Are you upset she's more popular than you?
I'm so far from being stupid. I'm jealous of her because she's more popular than me
You need to understand that supporting her and being there for her will help her be there for you too. You shouldn't feel jealous over her life.
I don't need her as a sister. I just want to make her life miserable.
It's wrong to feel jealous of your sister over her popularity. I'm sure you both have different personalities and she may just be more out going and social. Instead of being upset with your sister, ask her for help with becoming more social.
