Well, I hope you can give yourself credit for what are getting done in your life--it sounds like you are working hard at school and such. All of us could do things "just a little bit better." Sometimes we have to give ourselves credit for what we are doing. There is nothing wrong with being a little shy. Try to take small steps to engage with people. It is a tough thing to do--esp in a university setting--it can seem really overwhelming. Also, there are plenty of people who are shy and don't have a busy social agenda--you probably just don't see them. You are taking the first steps by talking about it here. Good for you! That is one thing you should congrat yourself on. I too am shy and I don't see anything wrong with it. I feel more comfortable having coffee with a couple friends than going to a party. I try to work on a few close friendships and I don't put too much pressure on myself to be the social butterfly. Take smalll steps.
