What is Normal?

Who is to say what is normal? For the past several years I felt that life in the Coleman house was that of 'normal'. The changes that have taken place these past few months, have led me to redefine 'normal' as I know it. What was once days filled with cooking, cleaning, shopping, running from one activity to another and finding time to sleep....has now turned into going to work and returning to an empty house or one where there is just one teenager who doesnt find it a whole lot of fun to just hang out with mom. So.....I am in the process of trying to figure out just what I want 'normal' to be at this point. (Any and all suggestions will be taken into consideration. lol..) At first, I looked at this challenge with remorse and depression, but now see that it can be anything I want it to be. That is a bit overwhelming and exciting at the same time.
I realize that I am not the first (nor the last) to have to figure this out, but I am the first in my family and I hope to come through it with a better understanding of myself and how I can make a difference for "????". (I will let you know when I figure it out).
For now, I think 'normal' is searching, questioning, happiness, confusion, crying, laughing, and wondering for me.... (the answers are sure to come to me as time goes on.....I am already not crying everytime I think about how my kids are growing up and away from the home...So I know THAT is a good sign)
