Being an aspie, I try not to blame my diagnosis for my ineptitude and lack of interests and spark of life. I'm rarely happy these days, I'm only content, and when I'm not content I'm depressed and angry at myself and my lack of special skills or talents. My self confidence exists only as a small shard of broken glass in the shadow of my self loathing. I am surrounded by people I find to be amazing, my friends. However, my envy breaks me sometimes, they're all good at something, amazing at other things, what's my talent? What's my specialty? What use, function and purpose do I have? I can never find a reason to love and appreciate myself. I keep trying to get into hobbies but I eventually lose interest and stop, it's like while normal aspies have few interests, I seem to have been born with none.
I'm not quite sure what you need help with. I immerse myself completely in things that I like to block out paranoid delusions that make me upset. If you're looking for something new then go out where there are lots of people and look around to see what catches your eye (I'm assuming you live in or near a city).
You're bound to get BETTER at whatever it is, and I'd rather be moderately good at something I enjoy, than REALLY good at something that's a slog.
So try a couple of things and see what really inspires you!
I recently thought it would be better if I socialized more, so I went to meetup.com and found this pretty awesome group in my area that aligns with one of my hobbies. I'm not trying to shill for the site, but it might be worth a try. Since the group is computer-oriented, everyone in it is ALSO pretty introverted, so mostly we all just sit around uncomfortably, but it's a START, darn it. And seeing them keeps me motivated to work on my hobby.
What's the worst that could happen, for reals? Even if it doesn't work out somehow, you're just back where you started, but you've gained valuable experience. You may even find some people going through the same stuff you are!
