I did internships a couple times before but never overseas. I felt the exact same way you did. New people, new environment, i felt unprepared and out of place. Anxious, clueless and frustrated. Somehow i made it through all of them unscathed. I generally just kept to myself and was friendly to anyone who approached me. And I'm not sure if I did my best at netwotking, but I still email my old supervisors every now and then. What was nice about those internships was that I always got feedback from my supervisors. Every single one of them said I should have opened up more and approached others more often, that this was my opportunity to learn and no one else has more influence on the outcome than myself. And that's what I would like to pass on to you. I don't want to get all cheesy, but there's this poem called invictus (I think, hehe) that goes like this "I am the master of my fate, I am the captain of my soul". You and only you are in charge of the outcome. They put you on the team for a reason, they believe you are capable of handling the work. You got this gurl!!
Some more of my two cents/things that help when I get anxious:
- breathing exercises/clearing my mind
- free writw everything that's on my mind, not worrying about structure or neatness, writing just to write
- possible ice breakers: any recommendations for restaurants, bars, music, etc? Any advice for a newcomer? How did you get your start at this company? Are you originally from this area?
- ALWAYS ask questions if you dont know something or can't figure something out, show's you're assertive, willing to learn, interest in company''s outcome and people don't like having to redo someone else's work (trust me on this one)
- bring in some coffee one day, write a little note them, and put it in the break room. But I would bring the coffee to those who you work directly with (person who oversees you, teammates, project partner...)
- schedule some time in to call or chat with whoever it is that's you're go to cheerleader for support
That's all I got. That turned out to be longer than I expected.
I wish you the best of luck! You got this!!
