This is a vicious cycle for an eternal life of pain.
Disclaimer : These are the symptoms of people who don't grieve because they can't accept what has happened instead of letting it sink in, pause and deal with the grief, they carry it with them like a heavy weight on their shoulder even though it's not theirs to carry. No, don't get me wrong.. it's not like they can't, they very well know how to process it but they don't want to deal with the possibility of a loss. They resist change, they're stubborn and adamant.
So instead of processing the trauma, accepting it, letting themselves vent and grieve. They just show up to work the next day after a loss of a loved one, they don't miss a single day of work since they think that's what keeps them going. They're hard working, quiet but as loud as they can be in other ways, efficient, ambitious in fact.
They're survivors, and the thing with survivors is that they live on their emergency brain and the thing with emergency brain is it responds too quickly, so anything that their emergency brain fails to process, it gets stuck in the loop as their emergency brain only keeps analysing without concluding, resulting in a vicious cycle where they basically torture themselves, unknowingly.
They now only have different scenarios associated with the memory and they choose the best logical reason to comfort us or to reason with. They instead of letting themselves feel the pain and grieve, choose to torment themselves with a lie, with a piece of logical reasoning in their brain. They choose an eternal life of pain by running away from it. They escape reality, they keep running away, choosing to comfort any other soul for a brief moment that they stay with and then they move on to substituting it by another person or thing to fill that void in them.
How to identify them? They lose their patience too soon, they're anxious all the time, there's always a rush, an edge to things, one race after another leaving them with no time to breathe, while fixating on achieving milestones after milestones. They end up crying on silly things like being unable to open up a lock, they get drained of their energy, end up getting hang and shutdown in every couple of months. But they always gather their pieces and pull it all back. They look really calm on the face though so you'll have to look closely, if you'll look at the signs voila! you've identified.
