I think you have. It's not so much about caring, but about obsessions.

You attach yourself to someone, maybe romantically. It starts off innocent enough, but the attachment gets deeper and deeper and begins to make the other person super uncomfortable, almost creeped out. As a result, they distance themselves from you more and more until they cut you off. You become more and more hurt until you realize they want nothing to do with you and utter devistation kicks in. That's when things take a super dark turn.

Hopefully you won't fall depper into this hole, because from my experience, it's very hard to come back out.
