<human>: I met my friend when we were lab partners sophomore year of high school. She was always super quiet and I could tell she didn't have many friends, so I invited her to a concert for her birthday. After that, she became very clingy to me and considers me her best friend. I'm fairly certain I'm her only real friend. 

For awhile I didn't mind bringing her around, except for the fact that I have to drive her everywhere since she doesn't have a car or license. An even more annoying issue is that when I take her to social events, she basically becomes my shadow and will not make conversation with anyone no matter how hard I try to include her. In addition, there has been a lot of times when I didn't want to drive because I could have ridden with other friends, but she basically guilt-tripped me into taking her.

Even though I don't feel like I get anything out of our friendship, I still remain her friend reminding myself that none of it will matter when we go off to separate colleges in the fall. But of course, she decided to follow me to college by choosing the same school I chose. 

I don't know if I'm a terrible person for not wanting to be her friend. She's a sweet girl and I don't mind being around her. I just want a fresh start at college and I want to be able to be independent. I know that she'll be all alone if I end our friendship, so I've stayed friends with her all this time because I feel bad for her. I'm pretty sure she knows this too. I just don't know what to do with her, and I don't want this to continue in college.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Friend is clingy and we're only friends because I feel bad for her. I don't know if I'm wrong to want to end our friendship.
