I can only speak for me.
I am a diagnosed mtf transsexual and was in theraphy and into transition from male to female.
I did not explicitly decide to detransition. I just did very small, very little steps to heal, to do what is best for me. My aim was and is to heal, to end the pain. To reconcile. To proceed transition was then simply too much for me, i have to live every day and i have had no energy or ressources for it. Transition felt not right at this moment then. First I had then some current problems to solve. So i paused transition then. Then i stopped transition. And live since then as a man.
I recognized then that i do not need to transition. Its better for me to solve my problems without the problems i have from transition like hormones, epilation, surgery, passing etc.
Detransition was not a goal, but a result for me from being truthful to myself on my way.
"This above all: to thine own self be true,
And it must follow, as the night the day,
Thou canst not then be false to any man."
(Shakespeare )
I distinguish between prudence, wisdom, science. Prudence can teach me what i can achieve, about my ressources, possibilities and energy. Wisdom can help me to recognize what truth is and a good life. And science can help me to recognize what is secured scientific knowledge at a certain time and what is not.
For example the concept of Kintsugi:
To see the force, the violence, the pain, the brokenness, to see the pieces, to fix it in the best way, to find a new wholeness:
I try to live a good life, learning to love myself, to cause no harm. This means to me to accept to be in a male body, to live healthy with a male past, with a transsexual past. To overcome my alienation and reconcile with me.
