Perhaps the hardest part isn't learning to coexist with our darkness, but learning to stop seeing ourselves as something that needs to be apologised for.
I won't pretend that changing the way you see yourself is easy, especially when those fractured parts feel so deeply woven into your existence. Nor do I think you can simply decide to step across a threshold when everything within you tells you to stay where you are.
But I wonder, why should your presence automatically be considered a burden? We all carry things that others may not fully understand, but that doesn't make our existence an inconvenience. You don't have to constantly justify your presence, earn your place in someone's life or apologise for being a work in progress.
And perhaps the door doesn't always need to be crossed all at once. Sometimes, allowing yourself to stand at the threshold without immediately retreating is a beginning in itself. You can take your time. You don't owe anyone a version of yourself that is easier to understand or accept.
You mentioned wishing you could see through my eyes. Perhaps I would only wish for you to see yourself with a little less harshness. Not as a fractured thing defined by its darkness, but as a person whose existence holds more than the parts they struggle with.
And one thing I genuinely believe: You don't have to apologise for breathing, for existing or for being human. Your existence is not something you need to earn.
Perhaps before learning how to let someone into your world, you need to give yourself permission to belong in it.
