i understand your feeling.
i can say to you as one of my CIEP teachers said to me this just a chapter from our lives.
you must live in it with all happy, and sad moments.
if you look around the university ,you will see international students from different countries all of them share the home sick with you
and i am one of them when i came to U.S i left my husband , and my daughter( she was 10 months).
just go ahead. God will help you
there is no gain without pain
