OK man, you need to pick yourself up, and realise that women are not the be-all and end all of life. Once you realise this, you can free yourself of your desperation... and actually interact with girls in a normal, fun, friendly way. You should introduce yourself to people you meet in your corridor and your halls, be friendly... not just to the hot girls, but to everyone.
Women do not like desperate guys - they like guys who are confident in themselves, are fun, friendly, and not afraid to say what they think from time to time.
