2 Day Before I Leave

I know the right way is to feel excited to go to a foreign country to experience a new culture and have an experience of a lifetime, but as the hours and minutes grow closer I can't help feeling nervous. Nervous, because I don't seem to be receiving any donations, I'm going to a foreign country for the first time in my life, this DTS will not as great as I've been supposing, that something will go wrong and all this hard work will be only be for a waste, that I'm not packing what I need, that I'm packing too much, and.. I'm sure once I get there and settle into my second week there that all these fear will dissipate, but for right now they all seem like plausible realities.
