Body image issues always led me to conceptualize myself as an entity inhabiting a body, the body being incidental.
I also felt this way until I started getting myself involved with physical exercise, and now I kinda feel more grounded in myself.
That might help you.
Oh I feel very much in touch with my body now, chronic pain forced me to do that against my will. I do exercise, though not enough. Honestly a thing that helped a lot more is being okay enough with myself to get out there and attempt dating again, and starting to notice trends among the compliments I get. Taking better care of myself now.
Still wish I could escape this body though, and get one that doesn’t hurt all the time and still has hair. Or to go full AdMech. To embrace the strength and certainty of steel, and aspire to the purity of the blessed machine.
