inner dilemma,  personal crisis, separation anxiety, depression,  cultural shock, all comes in the package of Existential Crisis, when I first arrived in the States in 1997 I was a mere teenager, it was a huge culture shock for me as I had to struggle that life had just slapped me in my face, I was in the age where my friends back home were enjoying life, where as I had to now work....that was new to me as I never worked in my life, So If i wanted to go to school, basically live life, I had to work and so I did, I found a job in an Indian restaurant but after a week or so I had enough of the dhoties bullying around so I beat one of the partner to a pulp( felt so GOOD) and challenged the owner to call the police BUT since the guy was illegal and he just paid me to leave. I struggled to fit in a job but later I found a nice job at a good place with lots of Nepali students, life was always tough because everything I made was barely enough to pay for school and live life, so I got another job, countless nights I felt that I was in hell and had to go back but the thing that kept me going were my friends who were struggling like I was, they felt everything i felt and we were very much alike and we were there for each other. Later on life wasnt that bad as we all started to fit in, finished school, got a job, married, kids, house and looking back i feel that those days were the best days of my life as they define who I am right now.
                I been through some real bad times and  in many ways I can relate to you bro. My advice is keep pushing your self no matter what life throws at you, remember its just a phase in your life and if you hangon against all the odds, things will fall in place slowly but surely. There were times in my life when I had lost all hope but the learnt  that the thing i had to overcome was myself, I wasn holding my self back,  once I tamed my self the rest shhiat the world threw at me didnt matter al all. If life throws a curve ball at you bro, learn how to catch it and learn from it. And lastly  a very good friend once told me" Tough times dont last, Tough people do". So Good luck
