Here's my personal take...
I often feel like I do something social...but when it's over, I usually go home and it's usually alone. I feel like I want my life to be filled with people, filled with doing things, filled with being busy all the time. Not having enough time to even spend any time alone would feel great. It seems. I guess I'm trying to make up for ALL the many years spent sitting at home doing nothing. I'm not, at this moment, doing very well with getting out, as I'm having a hard time meeting people. Plus, with my current situation I don't have any extra spending money, so even if I could find some people to do stuff with, paying for it would be another issue!
I find lately that I can't watch movies or TV or read a book without thinking- I wish I were doing something creative myself. Now me, I want to make movies and television. I want to write novels. I want to do stuff like that and be consumed with those tasks. So, I easily find myself envying anyone who makes a living making movies, acting, writing, directing. It takes the joy out of just viewing. I used to love to watch tv and movies (I did so much of it, I better have enjoyed it!) Lately, as I said, I just feel like I envy the person doing it. They're creating, they're keeping busy, they're active...no way they can be lonely, going home alone and wishing they had something to do, that sort of thing.
I think, for me, the biggest thing is spending SO much time these past many years not having anything to do, so I had to watch tv in my room or sit alone and read or surf the net. Now, when I do something, it never feels like enough. I never feel like I made a true connection, and if I feel halfway like I made a good connection socially, it feels like I don't want it to end, lest I never get the chance again. I want my life FILLED with these moments to make up for all the lost time and moments these many years. When life isn't just packed with them, I feel almost a failure for it. I have to remind myself that most people spend time alone each day part of the time, they're not constantly filled with things to do. I realize a lot of people that are social, which is what I so badly to be, DO go out a lot, DO spend a lot of time with others, DO spend less time alone than they do with others (and less time alone than I spend alone), but hopefully I can simply keep trying to make connections, figure out new ways to meet people, figure new things to fill my life with, etc. And I'll someday feel like I presume THEY feel on a regular basis.
Hopefully that all makes sense.
