Who am I NOW?

So, I'm pretty sure I am a loner.  As I get older, I not only like time alone... I search for it.  I like the quiet and peacefulness of it.  Weird....because I miss the hecticness (if that is a word) of a daycare and of kids running in and out of my house, and I think I genuinely WANT to WANT to have that, but somehow, the older I get the more I enjoy the quiet.  It's hard to except change in things, but even harder to except when it is occurring within your personality.  I have always been a people person... but I seem to enjoy it better in small doses.   Maybe it is an age thing... maybe it is a "stage" I am going through.  But I am ready to know exactly who I am again cause it is stressing me out!
