I've realised recently that I have become obsessed over this one girl, a close friend who things didn't quite work out with. There is no potential for anything to happen but I can't seem to lose my affections for her. She is a close friend who I can't avoid seeing regularly and I want to keep her as that whilst becoming less attached to her and more open to other girls. Liking her this much makes me anxious around her and makes it difficult to be friends.
