💐 for your experience OP.
My answer to your question:
Being a woman is a developmental pathway set at conception that is an unfolding of experiences throughout life; which may include the painful experiences unique to being a woman such as you are going through now.
I like to think of being a woman as a complex sum of the psychological, social, and ancestral, as well as biological/genetic and anatomical.
Being in my 50s, I am very aware of this ongoing process, as I am having to learn to let go of what it is to be a young woman, and embrace and grow into an older woman. Eg; letting go of pleasing and growing in fierceness and a sense of standing for larger community protection.
The phases of Maiden, Mother, Crone (true in some way for those without children too) seem very real to me right now; as something unique to womanhood and as something that cannot truly be appropriated.
I'm reading the book 'Nella Last's War'- diary of a world war 2 housewife at the moment. Not my usual kind of book, but I've been blown away by the connection I feel to a woman of my age, over a generation ago, living a very different life to me.
Some of her journal entries as she faces what it means to be a woman - in her family and community and society at large-the rage and compassion, protection, losses, unfulfilled desires, and frustrations, could have been written by anyone of us on here.
They could never have been written by a man.
Being a woman links us across time and space. That's what I mean by the ancestral part.
Apologies for length of this response, but the confluence of reading this book now, at this time, in the context of the battles we are facing, and reading your post now really brought all this home- and made me want to respond with my reflections.
(Recommend the book btw!)
