Hey Shygirl

In many ways, my struggle has been like yours. I've relied on the generosity of others alot too, but eventually I put in some effort and even made one long lasting friend in college so I hope my advice can help you.

I'm going to add to what Agentfyre and Raghib Ahmed have said and reinforce the importance of smiling and asking others about themselves.

It might be hard at the beginning, but when the opportunity presents itself for you to build lasting relationships, you won't regret it. Make sure that the people you smile at return the smile, otherwise you may be dealing with someone who is unfriendly.

Try to spot any people in your new classes that you've seen in other classes and decide for yourself if you want to speak with them; finding a common ground like past experiences is a great way of connecting with someone. Also, if you have any hobbies or interests, perhaps you could find a club or gathering at school to meet some like minded people.
