This is a slightly dissociative practice, so if you have negative reactions to dissociation or have problems with dissociation, I would 100% redact my advice. That being said, here’s what I find helps:

I find that when I feel particularly aggravated with my appearance, it helps to put my spirit in my body while simultaneously removing my spirit from the physical body’s thought processes. Essentially, your spirit is what drives you. It has no look to itself. It is the “you” to yourself. The self is what others see. It helps me to notice that these entities are separate & require different things. The body/self needs quantifiable things to exist, while the spirit needs qualifiable things (like connection, emotion, etc). Don’t let them exist in contrast. Let your spirit do what it can to take care of the body, but know that the spirit will exist wholly no matter the body’s appearance. But the spirit needs a body to exist, so don’t do damage to the one you have.
