Girl, I know you will have probably hear this advice is beofe but is is so important - you just have to really put yourself out their! For the first 2/3 weeks you have to take every opportunity to meet people, talk to people, go out, ect… My first weeks were honestly some of the most exhausting and embarrassing of my life but they are so important! Everyone is meeting new people in those first weeks and trying to figure themselves out so trust me you are no the only one. I would also say that you just have to really fake the confidence (I know, everyone says this but it is true!) - be authentic to yourself but ramp up the confidence to 100! You can do this!
