My Obsessions are not hurting anyone (a big one), years ago after a not so great relationship I use to obsess about seeing that person again, worrying about them, coming back to them as a friend (redeeming myself or being the person I said I'd be) It was a very phobic relationship actually...worrying about what my friends would think of this person. I told myself when I broke it up that "I would never treat someone like that ever again", which it self was an obsession. I would date people and just before I'd kiss them or something I'd remember this person's blue eyes and I'd stop cold, that was a fear of coming back to that person the same way (which EXPLICITIVE happened...total emotional car accident ). Generally, I obsess about purchases but I delay gratification (hoarding?). I'm actually running out of things to purchase now (can you tell from my checking account and credit score....yes) I'd actually say my biggest obsession is the intrusive thought of seeing this person again and trying to reason with her now.
