I think I might be manic depressive. I remember my break-up with my last GF was pretty nuts for me. At first I became obsessive and depressed. It felt like I had gone insane.
Then I became angry and plotted to kill her and her new "friend".
Then I just felt like I wasn't even alive. It was like I had gone so crazy I didn't know I was me.
Then I got over it.
Same here. 2 years, 4 months.
Except I didn't plot to kill her. Just her boyfriend/my bestfriend. I learned about several plants that, when treated right, produce toxins that can EASILY kill someone. Just spike the drink, watch them choke.
HOWEVER, (as a disclaimer) I don't condone murder and I won't teach you how to manufacture [EDIT] or the other poisons I studied. And the dude and I are cool now.
