completely confused???

This is an emotional post for me. You guys know when i first got to australia, i was feeling alone. The thing is it was the same way when i first went to college too. You feel alone, like you're thrown into this new world and expected to find a group or a partner in crime instantly and its hardwork especially if you're shy. well sometimes you go to events or just randomly you meet people and you feel like yes this is it, i've made a connection and then nothing. You see them around and its like they don't even remember who you are or at most you get a "hey whats up?" and you think to yourself, was i really not that interesting as a person that he or she decided i dont even want to get to know them? Its tough. Well, i had the chance to meet some great people in Australia and we had soem good times together but all of sudden they stop texting me when i use to get texts all the time, they stop visiting when i use to permanently leave my door unlocked so i wouldnt have to keep getting up every hour when they'd visit. I'm telling myself maybe they have a lot of work and they've been busy but facebook tells me otherwise. I cant help but ask myself WTF happened? why were we so close two weeks ago and then all of a sudden its as if we never met? I don't know guys, i assume that good friends will make time for me and i wont ask myself questions like this when it comes to them. Like my new friend from Loyola that i met here, i feel as though even when we leave Australia we'll still be good friends and hang out at Loyola, honestly i cannot say the same about other people from Loyola. nd even worse what about the people i met that aren't from Loyola, but from different parts of the world, i may never ever see them again, and im pretty sure some will write on my wall from time to time but others wont. They'll just be a bunch of memories in my mind. Of course they changed my life even in small ways and i'm glad to have met them, i just wonder what caused things to change so drastically? I'm not torn up by this, just completely confused???
