I cannot begin to explain how relative those words are to me. This has been my issue as long as I remember and I can never tell whether I'm hypo, depressed, or in a mixed state. I will always replay the situation in my head.

Over.

and over.

and over.

and over.

Until finally, after days of this (I went through 2 straight years of this after a breakup) I end up inventing how horrible the person is in my mind so that I have some justification as why it's beneficial they aren't in my life anymore.

What makes me more irritated and angry, than ANYTHING while I'm having repetitive thoughts, is knowing that the other person has already forgotten long about me and I'm the only one sitting wasting precious energy on being upset. 

Then I get more upset that I can't get it out of my mind. It's like, I've already spent months of my life not living in the present moment because I decided to be vulnerable and let someone in. Inevitably, they leave. I don't blame them.
