Simone,
My role model for constraining my emotions was Spock. I guess that gives a hint to our age difference.

Nevertheless, both of us seriously constrained our emotions for a long, long time.
I am not a psychologist - nor do I play one on TV. But let me give you my thoughts about how I dealt with a similar problem.
I know that I constrained my emotions to better control my own pain and frustrations. It was easier to not accept the emotional impulses than to address what i was actually feeling.
It took a long while before I gave myself permission to feel. I was afraid of opening a Pandora's box, but keeping the box closed was killing me, so i raised the lid. Old movies became my friend. Not the action flicks of my male days, but movies where there was an emotional ending. And they don't have to be "pure" chick-flicks, either. Movies with a great tragic hero are a wonderful starting point.
But movies isolates you from the world, and I was tired of being isolated. I needed to go out and experience life.
I go to the local Lilac Festival where you are surrounded by more blossems than you can count - where even
I can be engulfed in their fragrance. I watch approaching storms and let myself marvel at the sheer power of nature. I listen to the gentle patter of falling snow and savour the stillness. While others would curse the frozen world around them, I stop and gaze in wonder as the rising sun sparkled like diamonds on the ice-shrouded trees.
I found, bit by bit, that I laughed mroe. I listened more. I shared my thoughts more. I experienced the world, and I lived more.
This was before I started HRT.
Now, I find the world a wonderous place.
But it all started with giving myself permission to feel.
Just my two cents worth.
