Some time ago, I think it was around '06 I started meeting friends online in various games (mostly through steam).
I met like 50-70 persons during two years, everything was cool until I reached some point - I became... exhausted(?) of them. I wanted to get rid of them. I just removed everyone except some people I knew really well (at least I thought I knew them, I got rid of them later too). These people were just unbelievably stubborn, they kept added me to their friend lists after I removed them, like they wanted to know me. I started changing names, hiding from them.
There was one person online I met offline, I regret it to this very day. He was the only person that still remained on my 'friend lists' after 2 years of my hiding from online interactions. It's the most awkward thing I've experienced, as we both were socially retarded, we couldn't even talk properly.
After I returned to my house, I decided to cut any contact we had. I still don't know what happened exactly and why I did this. Somehow he found me later, after some months (I have no idea how), and told me how much of an asshole and idiot I'm (after telling him I did this intentionally, and I don't want to know him anymore), after name-calling me, he just disappeared.
I sometimes talk with some random people on IRC. I prefer to talk with people I don't know (this is why I prefer imageboards), so there is no chance of happening something like that again.
I never had any 'real' friends, maybe except one during my freshman year in high school (I dropped in the same year after 3 months, so it was rather a short friendship), but he didn't gave a fuck at the very end. I think I expected too much from people, this is why I got rid of the expectations, and of the people too.
And yes, OP, I feel jelaous, I'm jelaous of all people who can lead their lives like they want and be succesful.
