I have to admit. I have shut myself off from my body. Whenever I see myself in a mirror there is a little jolt of despair but I have learned to bypass it, and replace it with reassurance that it's my body and I live in it and there is more to a body than how it looks, and even then I am not the best judge of how it looks because I have such poor body image. I just bought a swimsuit last year for the first time since I was maybe 10. Since the age of 13 or so it was tshirts and shorts for me. Long before I ever had a 'problem' with my weight.
Is there anything you can do to distract yourself when your thoughts turn to body anxiety? Can you try to bring yourself into the moment and focus on things around you to defocus from the bad body thoughts?
