What is it?

There is a feeling inside my, it's the all too familiar feeling that I am always wanting to run from.  The problem is, I don't know how to label it. I'm not sure where it's stemming from. This is what I do know:

I tend to get this feeling in my stomach. It's a feeling of emptiness that isn't a result of hunger. I begin to feel "bored".  Yet, it's a feeling that weighs me down. I feel so restless with no ambition to do anything but sit. It's a feeling that engulfs me physically and mentally. It's a feeling that doesn't go away easy and likes to visit often.  

It is this very feeling that has lead me to try and fill it. Because it feels so much like  an emptiness that can be cured with food and/or alcohol.  Without stuffing this feeling, it doesn't seem to go away.  I wish I knew exactly what it was so that I could figure out how to treat it. 

Until then, today I sit with it. Today I will sit in this discomfort.
