when doubts arise

i've been living in another country for more than a month now, and, for lack of better things to say, its overwhelming. living by myself has never been my forte. i tend to stick to where ever it is that my family or closest friends are in. over a month ago i told myself that i can do this, that i have to toughen myself up for the long, bumpy road ahead. barely a few days into my second month and i feel like hurtling myself in front of a roaring MRT train just to take all the misery and doubt away.

talking to myself...over and over again...
i can do this...
come hell or high water...i CAN do this...
i have to...
Lord, help me, i have to...
