I know exactly how you feel, and I can really relate with Kyu as well.
I use to play this other online game, the first online chat game I've ever done actually. It was really fun and all, but the best part about it was the people I've met. There was this one person from a few others that I loved to hang out with, and always looked forward to when they came on. We would chat and hang out, and I was surprised at how much we had in common. I mean, it was like hanging out with another me almost!
It might be weird to have a friend like this only online, and maybe even sad and pathetic, at least to others, but I do have friends in real life but hasn't anyone ever felt like, well, they don't really care as much for you? That their likes and dislikes are completely different from yours and when your going through some hards times they may not show much concern for you when you would for them?
In real life, I had some friends like this but I could never get really close to someone because my family and I always had to move, so I have to leave my friends behind. I would only have a few friends because I'm not a huge crowd person, but when we leave I don't feel to torn apart because we just never seemed that close.
So anyway, where I was going with this was that I actually felt like there was someone who actually cared what was going on with me and if I was upset or anything they did their best to cheer me up, and I did the same for them. It was awesome and I loved every conversation we had, and I would be sad when either of us had to leave.
However, my friend was also sick, and I was being told that they may not be able to come on because their parents didn't want them to be stressed from the internet... If that made any sense. The sickness was serious, but I won't say what it was. So when they stopped coming, I was so upset... I hung out with my other friends from that game but I always missed that person. They didn't show up for months, until one day in the summer, they finally showed up! I was so happy I thought I would burst into tears with happiness! But then, of all the worse luck in the entire world and of all times to happen, my internet crashed! I tried to get back on as quickly as possible, but when I came back on they were gone...
I had never been so sad in my life, and I never saw that person again. I still went on that game, but going on it less and less, hoping to see the person again, but failed each time, until I finally stopped completely recently. It's almost been a year since I last saw them.
