Lonely. I don't recall ever being lonely. Alone, yes. Lonely, no.
I've never had many friends, and those that I called friends seem to be no longer so. I just broke with a best friend of 15 years. We were more girlfriends than male/female friends. (Transgenderism has its advantages.)
She did something that was completely inappropriate, blamed me, demanded to talk, and then refused to do so. She had a history of lying, among other things, and I finally broke our friendship.
Maybe the friendship was so unhealthy that there was nothing to regret. I find myself analyzing the situation, but feeling little if anything about it. I should experience the feeling of loss, but I don't.
Yes I'm alone. I've been this way all of these years. It would be nice to have someone grok what's inside me, but I don't expect it will ever happen. So be it. No big deal.
