I am a psychologist. I know the language of grief, ambiguous loss, individuation and attachment. I understand intellectually that children do not belong to their parents, that adulthood involves individuation and separation, and that loving another human being does not entitle us to determine the course of their life. That we have to accept them as they are.
Human beings need continuity. Families do too. Beneath all the ordinary changes of growing up sits a quiet assumption: this is the same child. The toddler, the schoolgirl, the impossible teenager and the young adult remain connected by a thread of attachment.
In my case, many of the familiar markers of my daughter’s identity changed within a remarkably short time: her legal name and sex designation, appearance, hormones, and body. My mind could not experience these as separate changes. Together, they felt like the thread connecting past and present was being ripped away.
