I know what you mean!
A lot of people think you get depressed and withdrawn after you spend a lot of time online, but for me it was the opposite! I spent two years primarily socializing on the internet, and a few months I spent completely by myself (apart from family).
During that time, somehow I developed self esteem I never had before and I had a lot of self worth and confidence when I dealt with people. It's rather strange, really, and I thought I was just a rare case of sorts, since most of the people I know who spend a while online do it primarily because of the problems they have dealing with people offline.
Unless I misread what you said! Then forget what I said. :X
I do find it really hard to meet people who share the same interests as me.
I had a lot of trust problems throughout the years. I would hand out trust like it's candy, and I'm really naive and foolish when it comes to finding people that I should be able to trust. I'm entirely too innocent in the world in that regard, because I figure that they won't do anything and aren't getting to know me to betray me or something of the sort. But I'm beginning to be a little weary on the people I trust, and I've become a lot like you in those regards.
I find it difficult to find people I can really trust as well. I've become someone with a very weary outlook on people's motives, and I've become a lot more difficult to talk to offline because of that. Always have questions going on in my mind. "Why is this person trying to get to know me? Are they looking for something? Or do they truly want to be my friend?" and things like that.
omg tl;dr! I so didn't mean for this to get this long... :[
