Okay, all of you sitting there and saying, 'I'm so unconfident, I can't make friends, it's so hard', stop.
Take a breath.
Who can fix this situation, logically? It's not your parents, or your friends at home, or nameless people on the internet. Hiding from the mass of people doesn't help you. The only one who can make you feel more confident is you.
If you don't feel it, fake it. Someone has to take the first step in a conversation, and EVERYONE is shy, nervous, a little apprehensive. First of all, smile, say, 'hi, I'm X,' and add a comment on your circumstances, ie, 'what do you think of this lecturer?' 'it's hard to go to class on a Monday after the weekend, isn't it?' etc. Nine times out of ten, the other person will nod, smile back and introduce themselves. Even people you don't feel WOULD talk to you - they're human.
Making friends, chat. In the beginning of a lecture, when everyone's coming in, introduce yourself to the person behind you, or next to you. At the end, remark on the lecture itself. Suggest grabbing a coffee before swinging home. Yes, you CAN do this with random people - they can either accept or refuse, ad either way, you're no worse off than you were before. I'm in my second week, and I have a couple of good friends who I've met this way. I'm considered friendly and self-confident because all I do is smile at people, and introduce myself.
If you feel, 'what if they think I'm TOO outgoing' - do what I do. My standard introduction (mind you, I'm a thesp, and an arts student, so I get away with it) is 'hi, I'm Alice, I'm just randomly introducing myself to as many people as possible, in the hope that like, one of ten thousand million wants to talk to me! What subjects do you study? Oh, cool, that always sounded really interesting in the course-guide. What do you think so far? Oh, excellent, I love knowing I already completely adore the things I'm studying. Urgh, getting here on time was absolutely awful, I was out at X society last night, what ones are you part of?'
etc. etc.
Join societies, if you don't know what's on, go to the Student Union, and ASK. Invite the person in the next room in for tea. Talk to the person next to you in your tutorial. University is a great place to meet people. You just have to take the first step.
