To be honest it wasn't that bad for me (it was what we were trained for) but it was a very sobering experience, seeing what used to be a beautiful thriving country split, divided and desolated. The people were lovely.
It's all kinda normal now, I so intend to go back some day.
When I got back to the UK I asked to go back. They sent me to Kenya instead,
Ps. But my god how cold was it. I live in the north of England and it gets bloody cold but minus 27 is cold even by our standards.
