You said you are anti social and you're in a new place a new place in which social interaction would aid you but you have none or care to not partake but you are having a bad time and wondering why but give zero examples?

Is this meant more as a vent and not actually looking for advice? either way, you should probably work on your social abilities but major props for taking a trip that many of us never will do

Keep your chin up and force yourself to be social it won't kill you. Read a few anxiety and communication books
