Heather, We all are afraid of making wrong decisions in this life...but we have to try to get out of that mode of thinking in order to move forward. Even if you make a bad decision, you learn from that mistake and will think twice before doing so again.
Just imagine, if Adam had not eaten the apple Eve offered to him, the world would be a perfect place and you know what? It might have just gotten boring after a while. Always remember, no one is perfect, but we do the best we can w/what we have to work with.
Don't be afraid to make mistakes...that's why erasers are on the ends of pencils. Mistakes can be corrected in time.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
