Is my mom being too smothering and obsessive?

So, to start things off, I'm the baby so it may have something to do with this. I feel like I've been an amazing daughter, but maybe too obedient at times. I've always done what my mom has told me to do because quite frankly, she's always terrified me. She's never abused me, I just believe I want her to always be proud of me. I've recently noticed that I'm always doing everything around her. I'm 18 and still living at home but I am clueless about how to do laundry. Even though I've told her I would like to do my own laundry, she refuses to even let me, let alone teach me. I'm still not allowed to have a facebook until I get out of the house because she feels like everyone will post bad things on my page and my boss will see and fire me or something. Also my boyfriend is a year younger than me and his family is just fine with me being in his room with the door open but my mother is totally against it and tells me that she's raised me better and I need more respect for myself. My boyfriend even claims that she's like a needy girlfriend because she'll call me when I'm at his house to tell me to come home because she misses me. I have to call her more than once a day to let her know I'm okay. Even my sisters who are in their 30s have to call her every other day or she gets worried. My mom doesn't even act like their mom. She acts like their needy friend or something and that's something she would never admit because she claims to believe that parents and kids should never be friends. She gets jealous of their mother-in-laws because my sisters would rather hang out with them than her. She's tried to make me promise I'd follow through with certain things when I'm older that I don't necessarily believe like marrying a guy before I move in with him. I believe you need to get to live with a guy and see what it's like before you make such a huge commitment. Both of my sister's did it and my mom still resents them for that. Sometimes I feel she just wants attention to be called to herself because she'll talk about what bad kids my sisters are and that she doesn't know where she went wrong in raising them when they're normal kids. I stay under the radar and do everything she asks so I won't have to be the main topic to her friends at work or my stepdad. She's a great mom. Don't get me wrong, but I would love some independence.
