Yeah. I guess I'm a bit used to it? It seems normal to me. I've been like this for over a decade now. Just working, getting by, and minding my own business. I have a cat. It doesn't bother me a whole lot like you might imagine. But even as a kid all my interactions with other people were pretty negative. So I kind of associated other people with being hurt and saw getting to be alone as an escape. I see myself as like a modern version of the hermit who lives in the woods.
Edit: To be clear by saying yes to estranged I mean like I keep them at arms length. I see them from time to time. But I don't tell them anything, and I don't trust them. I mostly just interact with them to be polite.
