Not sure if it's helpful but I think for many years I maintained a safe distance from myself, body, sensations, by absorbing myself in music, artwork, other projects...so also stuff that didn't allow me to totally cut off from my "self"...there was always part of me in those things I liked to do. Playing music actually helps me connect to my body in positive ways, but parts that feel more powerful through making music, like my arms (of course I over-did it and permanently injured myself...but I'm talking hours upon hours daily). I can relate to not wanting your body or identifying with it. But that doesn't mean it's over. There is just a "you" that is really hurt and identified with the hurt. It sounds like it's not feeling okay, and maybe not much better in how you can imagine things right now. But for the present, are there any things you like to do that do connect you or keep you connected to yourself in safe ways? Artwork, music, journaling, making anything, favorite authors, photography, taking care of something, nature, yoga, tai chi, etc....? I like doodling. I am pretty sneaky at staying connected to some inner self, and not letting that 100% disappear...many times I managed that without being connected to my body (or noticing if I was/wasn't). It's really helpful to connect to some little part of your "self" that has nothing to do with your gender or body parts, just your spirit, however fragile that might feel.
I do hope you keep looking for help. But don't give up on yourself. I know when I'm in my lows I can't imagine a good future. So I try to focus on the present moment and somehow make it more tolerable, reach out for help, or keep connected to myself in a non threatening way.
