English isn't my first language so I'm sorry for any mistakes. So I'm 17F only child and I'm someone who always have been a loner and I prefer being alone. But my mom is a loud, talkative type of person who always repeats herself and talks in circles and wanders into my room even when I'm overstimulated or overwhelmed to talk about something I do not really care about like politics, twitter, work relationships and marriage problems. She's always this cheerful person and is always excited and kind but it does tire me out like crazy because I really want to be alone. We live in a small house and wandering into my room kinda became the norm for her, she can just sit around on her phone on my bed or on the floor or on my swing even without talking but all I want is privacy. Sometimes I really cannot stand it and just outright tell her to leave because I'm tired but she gets sad that I'm kicking her out and tell me it isn't nice even though I try to explain to her I just want to be alone. I'm really wondering if I'm just too harsh and maybe she wants some company and I really do feel bad because she's a nice person am I the asshole for this?
