Why is my Ford f250 diesel super duty blowing out white smoke from tail pipe?

What is your question?

I was driving my truck early this week and noticed that when I turned over the engine a bunch of white smoke came pouring out tail pipe and could smell antifreeze. Filled with some water and had no problems until 4 days later my truck was sucking gallons and gallons of water, over heated and started blowing a black smoke. Now it is really sucking the water down even more. What is wrong?
