I am aware that not all alterhumans were born with their identity, so this question is targeted to those who noticed traits of them being nonhuman during childhood. Here's a part of my story:
"Close your eyes and open your souls."
Hello! My name is Xeep or Lucian, I am bodily 17. My pronouns are xe/they > he [I am a xenic individual]. I am an alien in every way, labels that describe my expreinces well are otherkin, holothere and transspecies. I have known about my identity since early childhood but discovered the alterhuman community about 4 or 5 years ago. I have a typing quirk where I replace 's' with 'z', but that occurs during intense shifts. I never do that as a joke. I'll provide translations to anyone who needs them, or just some time later. I also have other alterhuman identities. More: I like art and poetry, hate social norms, love and feel connected to nature, and daydream about fictional characters. I'm plural and my "alien-ness" affects many of our alters, as it's the most important identity.
