Anxiety Disorder with severe chest pain

I am a civil engineer who had come to U.S.A in june 2008. I am here till march 2009.
Recently i had this sleep problem started. I could not sleep for 3 days and i started feeling a bit anxious. i went to a doctor who gave prescribed me alprazolum (0.5 mg daily) but slowly this problem intensified. now recently  i startde having severe chest pains on the left side. Once it was so severe that i fainted in the office itself.
I have a strong feeling that as soon as i enter India-my home country i will be absolutely fine as i am missing my parents badly especially after suffering from this episode. But still 2 months are left and its really tough for me to even imagine that i will i continue here for 2 months.
Now i am having alprazolum (2 mg/daily 0.5mg 4 times) daily. But still i dont get 100% perfect. Is my thinkin right that i will be perfect as soon as i go back home to my parents.
Also please tell me how to deal with these chest pains.
Please help.
