More the opposite, alone but not lonely. But there are times of loneliness. Not often. I assume just about everyone has felt lonely at one time or another. Whether alone or not.
Good question - even my shrinks have had difficulty figuring that out. But they haven't been that sharp.
My two best friends don't live in the same country as me anymore and they're two people ive never been able to replace in my life. I know a lot of people now and can meet new friends quickly but I've never been able to replace those two outrageous people in my life. In a way I can feel lonely with things like they are, off remenissing about the fun times. Now when I visit them all is good but there's just a big gap now of awkwardness. It's like we can't talk about the last 7 years. There's us at 13 to 25 or 32 that's it lol
