Leaving my mom

I move into my dorm on Wednesday and I'm so sad to leave my mom. I'm excited to start college and everything and my mom only lives an hour away but I know I'm gonna miss her so bad. Every time I just think about packing my clothes and stuff I just break down into tears. I can't drive to go see her but my boyfriend offered to bring me back home. I just feel like I'm not ready to grow up, I just want to be her baby forever. Every time someone mentions college she tell me that she doesn't know what she's gonna do without me. I'm her last kid and I don't wanna leave her alone. I know I can't like drop out but I wish I could. I feel awful and I don't know how to deal with this.
