Checking in again from left field...
(I have not been through a nasty divorce; disclosure.) I do have issues with making connections, then maintaining them if I accidentally make a couple of steps forward.
I was thinking more about the 'why?' of it-replaying the crap over and over. The attention aspect of it, imho, is a clue.
Could it be associated with making connections with people? We are social creatures and are wired for fellowship, so I am told.
Is it an instinct to be so desperate to cling to negative connections as better than no connections? This is in agreement with what NeedAFootMassage said. And could be a good question for a counsellor.
Deludedfool, my initial thought for 'adrenaline' is (I don't mean this to sound harsh or insensitive) to link it with "sport" in the same way people get adicted to extreme sports for the physical sensation. Would this make sense? Complex because we get the feeling that, for example, an intense martial arts class would not be the remedy. Imho, again, it may be tied in with the connection with people aspect-creating a complex web to resolve.
The feeling lost without it, could be because the void creates a vacuume, and that will pull you straight back to it...fill the void with something else (we're talking about something positive, right?
).
Sorry you are going through this, FeelAshamedByThis (and Deludedfool)...you shouldn't feel ashamed, btw...you feel what you feel; don't dumb down/numb your feelings, you need them.
