The original thread of this message began some 3 years ago, though the message is still very much "NOW" for people who are trying to get over a breakup.
The above message sounds suspicious to me - not that the poster isn't suffering or painting an accurate picture of what happened to her, but that seemed to be an absence of red flags. I would gently recommend that she check out the Narcissism/Sociopath Forum here, at Curezone.com. "Falling in love" with someone as quickly as she described is often a symptom of narcissistic behavior - whirlwind romances that are based upon immediate gratification are common.
Getting beyond the damage that a narcissist leaves in their wake takes time and an understanding of the personality disorder. Sometimes, there is no closure or finality where an NPD is concerned. We want to know why, how, and "why me?" For most, there is no answer and we have to become content with the fact that we were spared any further damage.
No man (or, woman) is worth such anguish, particularly with regard to prescribed medications. You'll be just fine! Best wishes to you in your healing.
