Where am i?

Here i am, exhausted, still trekking my way through this unmarked territory in panama. All my friends are dying from these horrible diseases like  Malaria, Yellow Fever, dysentery,and typhoid. Not to mention i am dying of this tropical heat. I don't know how much longer, my eyes are going dim and the light is so faint. These conditions are absoulutly terrible. If i die tomorrow tell my family i love them.
