Based on your posting history, you seem to be an extremely insecure person; so your problems are likely very deep. But here is my suggestion which worked for me as an expat alone and in a country where I didn't speak the language. Get out and mix with people in the markets, stores, on buses or wherever, since you'll never be happy or successful staying home wondering and worrying. Yes you will be lost and confused and people may laugh at you, but who cares and it won't hurt; take some money, a map and get out there. I'm not an extrovert, but I got to enjoy just seeing what would happen next and learning about life from a new perspective. It made me a much better person.
