my first time 13 or so years ago i was the same ....mind you it was even more basic then!! ..... I also cried and wanted to go home and like Les i live here now so as said previously 'go with the flow' and you will love it hopefully,
few.... tips dontt tip loads at the airport and do not let them intimidate you .... for money i mean just say no!!
barter where ever you go as otherwise you will pay far too much and just carry wet wipes to wash your hands before eating as you will shake hands with so many people,
put your mozzie spray on before you get bitten morning and evening there iis about an hour each end of the day that they go mad hthe rest not too bad, and enjoy!!!!
