My Mom title is not what it use to be

I am sitting here on a Friday night, and just finished listening to Phoebe Snow sing "Somewhere Over The Rainbow" on my YouTube ....and I realized while hearing those beautiful lyrics I miss my son terribly. I haven't felt the need to tell anybody, I haven't spent time with the feeling, but there it was right there in front of me. Adam has moved on, I did my job, and I am feeling it. The Empty Nest. How can this not be expected? Imagine for 19 years my life revolved around this person, I scheduled my career around his life so I could be more involved than not-but knew the importance of having a career so he could learn the value of his Mom, or any woman, should have a balanced life. He saw how much I loved Radio broadcasting, he watched me weep when I was let go of the many;gigs and he watched me move forward when I knew I should, to train for voice overs. He saw me fight my 2 cancers, he saw me furious with his father, he saw me value my friendships with my girlfriends, he saw it all...and now he moves on to discover his own independent world and here I am on a Friday night reflecting on all of it.I have to redefine my position now, I have to feel okay with where I am, for the time being. I am really feeling the unsettled feeling I am not comfortable with. My Mom title is not what it use to be.......:(
