A similar question was asked a two months ago:

I'm a Christian peasant in the 14th century Balkans and the Ottomans have just conquered the place where I live. How will my life change?

I'm actually not very happy with the depth of the responses there so I hope someone can shed some more light on the issue.

I'm a Greek peasant in 1453. I have just received word that Constantinople, hundreds of miles away, has been conquered by the Ottomans. How is my life going to change?

These responses are better but the geographical scope does not correlate to your own.
