Really enjoyed reading this post as I am about to take a gap year. I have mad set plans that I cannot back out of for just this reason. I am very capable of doing exactly what you did and am gradually for the reminder your post gave me!
I am a firm believer of the phrase "don't cry over spilt milk" as there is no point spending thought and energy on what has gone wrong when you could be think about what could go right.
Very thought provoking post for me so thank you :)
