It is difficult to appear strong when you are actually weak.
It is difficult to smile when you really want to cry.
It is difficult to be patient when you really are very eager.
It is difficult to tell people that it is not okay, because they will advice you to not do it and you know you have to do it.

I know I am writing only about what is difficult but that is how I am feeling now... frustrated and weak...

I simply feel that I should have not come to the US... I am suddenly feeling distant from India.
