My Parents Love My Younger Sister More Than Me! What Should I Do?

I’m Sara. This is my sister, Laila. She’s four years younger than me. Unfortunately, my family loves her more than me. I’m not even sure if they love me at all. Actually, I’ve always been aware that my parents have been nicer and more understanding towards Laila. It had never bothered me because I thought it was normal for them to treat her this way since she was younger. But recently, after everything that has been happening, I began to suspect that my parents just like Laila a lot more than me. I’m going to tell you about everything that happened.
