I couldn't cry for 10yrs or so. 16-26 yrs old. That could be the trauma related to POIS, yet I couldn't even feel that feeling in your throat for yrs. I call it POIS emotional numbness (you feel too much and then nothing at all). It's horrible.
After that, I found that I can cry and it is erratic and related to a POIS episode... The smallest thing that makes no sense can set it off. I also found w/ this crying switch my symptoms did intensify around 26yrs old. More than anything it is switch between a hyper-emotional state and flat affect with overwhelming numbness. I have talked to psychiatrists and psychologists who are aware of POIS about my switches and they say it is not bipolar and more an anxiety-driven, OCD-fueled emotional state, which switches to numbness to compensate for the overwhelming feeling. Almost self-protective. But we all understand that POIS anxiety/OCD differs from many other forms in that our bodies go into a hyper-arousal as well. Not somataform disorder, which cannot explain some of our physical symptoms. Or perhaps we epitomize somataform, yet science is finally looking into the body/mind impetus...? I don't know. All I do know is this shit is not in my head, but sends my head off a cliff when it goes haywire. It feels like body then mind, then cyclical when things escalate, which is why psychiatry tends to handle use more often than anyone.. Clearly, they don't know though. And, I am convinced POIS is regulatory with possible autoimmune connections...
