I think it's about a relationship that ended years ago and kind of "traumatized" the speaker.They are afraid of letting people go, that's why they "sacrifice their soul" doing everything others want just to please and maintain them close. Even though they do this effort and have people they love close to them, they miss their ex-friend/ex-boyfriend/ex-girlfriend a lot. Looking back is frightining and pleasureble at the same time: "everybody scares me but you/ nobody scares me but you". The memory of the "better days" is sweet but also hurtful because it will never come back.
