February 2012. I'd gotten in to a very warped codependance with someone and it was tearing down all of my defenses very very quickly...and it's also a very long story. The person I was having the issues with sent me a link to the DSM with the note "Does this sound familiar?" I read the nine traits and I know my mouth must've opened wide. I related to every single one of them. Even though I knew it, I was in a bit of denial until I came to PC and saw so many with similar issues as me. I was officially diagnosed January 2nd of last year.
