Dry land

I need prayer. I seem to be in a dry land. There is no water anywhere in sight. No help just me sitting in a desert. I can't seem to find the strength to get up. I am physically sick. Mentally drained. With no will to go onward. The only light I possibly can see is the glimpse of Mexico. But that is slowing sinking to but a small blink far off. I can not find anything to live for. Nothing!!
