Similar but different for me Lost... But I can relate. My introversion has led me to a different path and currently a different regret.

I like Rohag's observation and idea. I think with a little work you could find something that suits you. For me computer coding has always seemed like a good path where I could work alone and thoroughly enjoy and accomplish something, I just haven't been able to drag myself there. Hope that you can find your place and some satisfaction for your life, I believe it is possible for you.
