Don't be so hard on yourself. You aren't a loser because you aren't that social. It is just your personality. It's part of what makes you you. I have always been a very shy person. I mean, I am fine with people I know, but put me in a room with a bunch or parents I don't know or something like that, and I will just stand there. Even if you are shy, that doesn't mean your kids will turn out that way. My son was very very shy. Even family that he didn't see on a regular basis, he wouldn't talk to. When he started school, it did wonders for him. He has more friends now than he can count. You might try putting your older one in a team sport like soccer or something. If you have one of those kid gyms like My Gym around you, you might join something like that with your younger child. All you can do is encourage them to make friends and put them in environments where they can do that. But, if they do turn out to be shy, don't sweat it. I've always been that way. It's just the way I am, and there isn't anything wrong with it.
