Is it normal for my sister to be this insecure?
Shes probably one of the most insecure females I know. Shes paranoid about her boyfriends talking/associating with other girls (yet she has multiple boyfriends). She downtalks other girls because they are more attractive than her, or blond. She criticizes me about everything (I'm pretty sure shes jealous of me).
Whenever we are at the gym, she always tries to compete with me..its annoying. I'm just trying to work out to better my health and get swoll, yet here she is getting all pissy because I have high endurance with heavy equipment and what not. I give her credit for being a better runner than me, but if for once I want to run faster..she assumes I'm trying to beat her and ups her speed up to mine. After leaving the gym, she talks about how every guy in the gym was looking at her and that their girlfriends were giving her the deathstare for it. I highly doubt that is true. Its like she has to get approval from guys, and other girls have to be jealous of her in order for her to feel good about herself. Is this normal? I feel its not because unlike her I'm highly confident or don't really care much about what people think of me.
