Hi Sofa00,
First thing I thought about when reading your message was the description of some kind of dissociation between your mind and body and I know that to be associated with depression and/or anxiety and/or trauma as well as other reasons I suppose.
I hope that you've spoken with your doctor about how you're feeling because the sooner the better. I wonder what happens if you try relaxation techniques. There's the old tried and tested one where you lie down and while starting at the toes, you tighten and then relax every group of muscles until you are all the way up to your head.
Progressive Muscle Relaxation: Benefits, How-To, Technique
Apart from all the benefits this has, I wonder if it might enable you to get in touch with your body more just a little, gentle bit at a time.
Just my thoughts.
Feel better soon.
