Interesting that this thread was both started and resurrected around Christmastime. To answer KokoCollino's questions in the OP:
Are you happy and satisfied with your circle of friends?
I don't know if I have enough friends to form an actual circle.
But I am happy that I have at least one close friend who I'm comfortable enough to share pretty much everything with, even if this was a friendship forged online.
How did friendship change for you over the years?
I think as a student in elementary, middle, and high school, most of the friendships I had were borne out of just being in close proximity with people for seven hours each weekday, as opposed to a genuine connection. Even in college, most were formed through group projects, and kinda fizzled out as we went on to different classes. And at work, I think it's more of a survival situation, like in the Hunger Games, where you find a group of people to go through a terrible experience with, and you guys help to keep each other alive.
Are there any challenges you want to share with us?
Being gay in a homophobic society is probably the biggest barrier to me making friendships. I think I had some close friends in high school, but when I came to terms with my sexuality around 2011 and realised that these friendships would probably die a quick death when I came out, I think I decided to just let them die a slow, drawn out death instead. Beyond that, though, I suck at friendship maintenance - I'm not great with regular communication.
In re-reading what I wrote above, it sounds rather depressing, but I don't really 'feel' the friend deficiency as much because I'm super close to my sister (even though she routinely annoys/frustrates me), fairly close with two of my cousins, and I have a few friends online that are pretty awesome, too.
