Day 11 ~ Bad Day all around

I have been struggling for some time dealing with a lot of life changes because I want to make the change it excites me and challenges me and gives me hope for a better future, but then fear sets in and change seems scary... How do you decide, not only that but then their is God's will for your life and how do you discover that? Let alone fulfill it? What if you go in the wrong direction thinking it is right, will you know, if so how and what do you do about it then, is it always reversable or are there things that can't be undone?
Obviously all these questions are ageless as long as man has desired to do God's will these questions have been pondered and everyone will have their own creative answers or none at all... I however really want to know the answers or at least how to find the answers. I hear the spiritual answer read and Seek God's word and it will be revealed to you. Does that really work? Prove it. No I am not questioning God or His Word. I believe in them and I believe they contain all the answers but How do you find them and when you do find them how do you know that is really God's will and not your own fleshly desires? How do you "just know"?
So if you know then let me know... lol you know!
