I Push People Away

Painfully Ironic... I have a really bad habit of pushing people away in my life with an ungodly intent.  I am good at it becuase I can use words to cause destruction in the most henious way possible.  I don't do it usually unless I've been hurt, but if I have, watch out as there's no limit to my wrath sometimes.  I always regret it a day or two later and feel really bad about it, but it's always too late to fix it.  It's a defense mechanism I learned when I was growing up.  I can rarely fight it away as it comes out so easy and happens so fast.  And because if it, I have no one left in my life.  Deep down inside I'm thinking 'get away, get out of my life so you cannot hurt or cause harm anymore' and I succeed in that.  The most painful part and most ironic is it's always someone I truly love.
