Writing a letter from a desert island

My name is Berta Rodríguez and I'm writing this from and island near Madagascar.
My dog and my friend are here too.
We are lost and we cant communicate.
Life is very funny on this Island.
We're having fun here but we're missing our families.
We can't survive here. It's very hot and sunny.
There is a lot of food. We sometimes eat tropical fruit and fish or shellfish and we drink rainwater.
