My cousin sister is really annoying sometimes. I recently lost all my friends, and it's a sensitive topic for me but she still does not stop talking about her friends despite knowing about it. She always wants things to go her way and is completely invading my space. I like being left alone but she just wouldn't give me space. She's ALWAYS there and I'm getting sick of it. Also, she gets too close and corny with my brothers, constantly touching them and calling their name even when they are angry or are screaming. She constantly keeps asking if we'll miss her when she goes away. I am kinda possessive when it comes to my brothers so I DO NOT like it when she follows my youngest brother everywhere he goes and is constantly trying to touch and hug him. It seems creepy in a way.

But she is also a single child, so I can't tell her to fuck off if she shows an affection too great towards my brothers. And her family agreed to extend their visit while my parents have gone out of town because my father needs a stent to be put in his artery. So am I the asshole for being annoyed by her? Because she is just too clingy and perky for my taste and she is constantly touching my brother. And she just goes all silent when things don't go her way.
