Road Block, Shower Block, Writer's Block

I have the dreaded Writer's Block.
It's horrible.
I haven't been able to write much without deleting it all.
I think I know why I have it.
It's not because of the usual lack of inspiration.
It's because something has happened recently that has made me really angry, upset and all sorts of other negative emotions.
And I am consumed by these emotions though I try hard to fight them.
I just can't figure out how to get rid of these negative vibes.
Just when I think I've finally let go, they come back and slap me.
I'm really disappointed in myself for letting such an insignificant thing bother me so much.
*sigh*
