I'm 48, don't have a family, don't want one. In my twenties, I thought I might want a family because everyone said how happy it makes you, so I figured if everyone said it then it must be true. but I could never imagine myself married, and the thought scared me. I'm glad I didn't. it would probably make me miserable.
I feel completely disconnected from everyone around me and always had, since I can remember myself. I feel like I'm walking in a fog, and this world is completely unreal to me. I'm just floating in it. other people are robots or aliens, or both. I have no idea what they're thinking or feeling, or if they are actually capable of real feeling. I don't know what is real and what isn't, so I can relate to what you wrote.
