The language of "your life"/"your brain" implies some true you has a separate existence that possesses the body. English as a language seems predicated on the notion of an afterlife.
[edit 11/15/2021]: After reading The Denial of Death and Love In A Time of Loneliness it’s more like the identity composed via the symbolic self has a body.
"Indeed, we have a body as an effect of language and the distance created by this language.
[...]
The organism acquires a first mastery, a first identity by means of an externally imposed unified image of the body. This unified body gets translated into the master-signifier “I”, to be understood as m’être à moi-même/maître à moi-même (to be myself, to belong to myself, to be master of myself), an “I” that has a body and has lost its being."

"The signifier represents the subject who is not psychotic. The subject is in the place of meaning; he is what is meant; he is what is signified for (pour) another signifier, by/next to another (auprès d’un autre). Of course, this is never completely accomplished, because there is always a remainder: the object a. In psychosis, the articulation with the second signifier is missing. A signifier replaces the subject completely; it does not represent him. This signifier does not need to conjugate with another; there is a coalescence of signifier and subject (meaning). There is not an inassimilable remainder, a residue of the operation. The psychotic is invaded by a jouissance from which the common, “sane” person is excluded. Words are things for the psychotic. In psychosis, there is an S1 that represents the subject in an absolute manner, without remedy, remission or any symbolization of lack. This is why, let me insist, we speak of psychotic jouissance and not of psychotic desire. There is no lack that would put discourse into motion."
