Feeling alone, wanting to get off this earth.

Today I'm feeling alone.  I thought I had the support of my 2 sons, but guess I don't.  They both made it clear that they feel like they need to be here for me.  The irony of this is that neither one has done much to help me since Chuck died.  I won't bother them.  They can call me if they want.
So, I have no one here where I live.  I have my work and coming home to a quiet empty house.
I haven't gotten much sleep lately, so maybe after a nap, things will look better.
