Why Writers Become Alcoholics

I would like to preface this post by saying...I am not an alcoholic.  I am not drinking now. I was stone cold sober when I wrote every piece on this blog.  What you are experiencing is not the result of debauchery but merely bad writing.  Please do not schedule any interventions or send me the names of rehab centers.  Some recommendations for a good therapist might not go amiss.
 
However, as I have been writing more, I have become more sympathetic to those authors who go right off the rails. Here is my list of reasons why writers become alcoholics (or go insane, or become hermits):
 
1.  Because writing makes you actually look into your own brain and think through your own ideas.  Don't think this is tough?  You haven't done it.  You've never written yourself into a corner and wondered how you got by with such shabby thinking all your life?  You are not trying very hard.  It's painful and disconcerting.
 
2.  Because  you need a little bravado to take the edge of those things you know are going to really annoy and offend people.  Writers are trying to tell the truth.  People don't like the truth.
 
3.  Because you pour your heart and soul into a piece and the only feedback you get is on a comma splice.  Or a spelling error.  Or  sentence fragment.
