#3 Get help.
I remember the first time an Italian friend of mine asked, "what's networking?"
I told her it was when you talked to friends, family, and colleagues about your job search and job-related problems and asked those people for suggestions, connections and guidance which could help you ameliorate whatever it is that you're dealing with.
My friend responded, "you have a word for that? In Italia, that's just what family and friends do. There's no special name for asking help of your family and friends. And everyone within a 20 kilometer radius will be willing to help."
When you arrive in a new country, your network is immediately smaller. How many people do you trust in this new place? How many people whose opinion you care about? How many people who know you well enough to offer helpful, useful advice as it pertains to you as an individual?
If you don't want to talk to your friends because you're worried about being judged, then talk to your family. If you're worried about talking t your family because you don't want to stress them out, then talk to your colleagues. If you're concerned about talking to your colleagues then reach out to a coach, peer, or mentor.
All I want to express is that help is out there for those who seek it. As an immigrant or international student you are dealing with A LOT. If you're struggle is organizing your job search, find someone who is organized and get some feedback. If you're struggling with resume and writing skills, find a good communicator and ask for some suggestions. If you're struggling with your mental health, worries, stress, (all normal things), reach out to a counselor, mentor or coach.
Take a deep breath. :) You don't have to do everything on your own. :)
