"trigger warning - therapy talk"
My whole life I feel like I've lived all my life in my head, it's not an articulated world, but more like whenever any type of decision, confirmation, contact...anything had to be made in the outside world, I would sub-route off in my Internal world and every and all outcomes were negotiated in there.
It doesn't matter if I actually follow through with the actual situation, I will make up every outcome imaginable in my head and live them all out to their conclusion.
I once had a T describe it as "Philosophers Syndrome"
Since starting therapy I have been introduced to Seperation Therapy...a sort of guided imagery. The first room you are led to is the "bad room" for lack of a better term. Mine is an attic. Old wood, creaky floors, with a HUGE stained glass window at one end. Landmines are all over the floor, and everywhere are stacks upon stacks of packed boxes. All labelled with different years, or periods in my life. I know all these boxes are packed with the memories I don't have that have been hidden from me by my Others (years birth to 15). This is an interesting room.
Go through the window to find my "good place". Turns out its a tropical island, with amazing wonders and delights...but those are just for me

I just thought I'd throw in a bit of my world, it may help you with some clarity on your own journey!
