There's a strange sort of somberness to not having anyone to talk to. I'm not sure loneliness fully describes the feeling.
I think I understand how you feel though OP, though I'm not sure I can offer any healthy ways to deal with it.
I suppose if you think you've been coping well with it, then that's a good thing.
Sorry if this was incomprehensible or hard to follow, I'm hungover as shit.
