I had an encounter with a close friend of mine at work tonight. He asked if I wanted to go hang out with him and an old friend of mine, whom I never hung out with much outside of how we knew each other. He eventually got irritated after asking countless times to go and wanted to know why I wouldn't but I didn't have a real answer, I just had no desire to go. Apparently him and his father made a bet this morning if I would go or not and his father won this bet but for the wrong reason "He likes his video games too much to go out". This is a bit upsetting to me but hey the truth hurts, whatever, so I shrugged it off for that time being. My friend had the right to be irritated with me though, there should have been no reason for me to not want to go and here I am sitting at home since 7pm and I've done nothing productive so the time spent with friends would have been better and I know it.
I've always been this way, I've never liked social events, family gathering, or going out places. The only time I get social face to face is when I am forced to go out or forced into the situation. A few times when the same friend sporadically invited all of his other friends over, I stayed and hated it or left early with an excuse. I don't know why I am this way and don't know how to get over it other than "just doing it". I can easily say that this problem is in the way and has been for a long time. Does anyone have any input on this?
tl;dr
I am antisocial, sad, and depressed, feel like I am accomplishing nothing, help.
