Setting emotions in motion

Lately, I’m often, usually, feeling empty of emotions. 

After all the turmoil and roller-coaster of emotions from the past year — discomfort and anxiety from the place where I was living (i.e. the person with whom I was living); fear and trepidation for my gender-affirming top-surgery; relief and joy in the new place I found to live and opening up to springtime, summertime, and life again; joy and love and excitement in the romantic relationship with my European queer ex-lover; and then also pain, sadness and anger related to them; grief and sorrow around my father’s final hospitalization and death; pain, effort, and anger around having to defend/protect my boundaries from some attacks coming from people I love — now I feel almost uncannily calm, grounded, centered. And often almost empty of emotions. Or far removed from deep/strong emotions and only able to feel “superficially”. 

Often now the only things that bring back strong(er) emotions to me are related to getting into my body, connecting with my physical self, through (intense) exercise, sex, music. In order to feel emotions, I need to set my body in motion… 

Is this a “natural”, “physiological” phase of sorrow or post-grief?
