Floundering in the Historical Ocean of Thought

Today is one of those days when I look at the road ahead of me and wonder if I can actually make it through it all. I know what I want to do. I know the direction I need to go in. I'm just not sure my strategy for the obstacle course. Right now, I'm working on doing research for my Thesis and I find myself floundering. What direction to take this Thesis is proving to be very difficult.
I know that Witchcraft in Early Modern England is my basic realm of topic. But the more I read from other historians, the more I fluctuate within that topic sphere. I just keep coming up with more and more interesting directions and questions.

What is reality for these people of Early Modern England? How did they view their own world? How did that factor into the question of Witchcraft? Everything from gender questions? Power? Religion? Identity- both of the country and the individual? Crisis on the Domestic and Foreign levels? Monarchical power? Henry, Mary, Edward, and Elizabeth?

On the very basic level I can see a swirling, mingled whirlpool of how all this interacts and intersects into the question of Witchcraft, but how do I nail it down? How do I take all of this and find evidence in primary sources to back some sort of argument? This is where I am struggling.

I thought I had this idea about how Witchcraft was determined by the the dominant religious force's decisions based upon what was 'good' and what was 'evil'. This was usually based upon saying that magic that was associated with the religion itself, ie miracles, was good and all other forms of 'magic' where 'otherized' and therefor bad. This further was influenced by other religious ideas based on power structures within the society. Therefore, women in the society who stood out and didn't follow the social norms where lumped into the same 'otherized' category as the 'magic.'

This still feels like a very valid point in my mind, but there are so many other ideas rolling in my head concerning so many other questions. Is it possible to take all these ideas and mold them into some sort of Frankenstein historical argument that works?   

Changes

Up until this point in my graduate career I have pursued what has been one of my great loves in history: The Ancient World. Specifically, the period of shifting from traditional Greco-Roman religions (paganism) to Christianity. I was researching and fully intending on writing about the discourses of magic and how it all fit together in a complicated and tangled web if power structures.
Then the struggles occured and a crisis of faith hit me. This wasn't where my heart was. My heart lay in the field of Early Modern Britain, with its witchcraft trials, its gender conflicts, religious turmoil, and poltical revolutions that were tied up in theses issues. With the country's struggle to establish an identity that seperated it from the continent. This is where my heart had been the whole time.
Yes I loved and still love the ancient world, but England/Britain has always held a fascination for me. That is what I have to follow. Will it add a year onto my Masters? yes. Will it mean more work? yes. But in the ed i think i will he happier for it.
