Well usually the youngest is shown a little more favoritism because they're the last one so parents usually don't want them to grow up too fast (I'm the youngest of my siblings so I can relate) but this sounds more serious… It's not healthy for her to shelter herself from other people like that at 10 she should be making friends, playing outside, even hanging out with you… She's going become a loner and it might get worst over the years. Try suggesting you guys hang out and maybe have your mom and dad talk to her about doing something other than mine craft

Maybe your mom just feels sorry for her cause she's got some problems
