Nope, I absolutely don't feel the need to ascribe my negative habits to some fear or anxiety whatever thing. Not everything in life is a drama. I am fully aware of my strengths and weaknesses, and my personal opinion is that ascribing a negative trait (procrastination) to something that is somehow "external" is a subtle refusal to take responsibility. Often (and I am not saying this is the case for OP) the "oh, this is a fear or anxiety I have" is followed by either the direct or implied expression of "so it isn't really something I can do anything about right now".

That is the attitude I found to be holding myself back in a dark past. What turned the page for me was reading "Invictus" from Henley, who was a man that was absolutely beaten and battered by life, and still refused to give up:

  Out of the night that covers me,  
  Black as the Pit from pole to pole,  
  I thank whatever gods may be  
  For my unconquerable soul.
  
  In the fell clutch of circumstance  
  I have not winced nor cried aloud.  
  Under the bludgeonings of chance  
  My head is bloody, but unbowed.
  
  Beyond this place of wrath and tears  
  Looms but the Horror of the shade,  
  And yet the menace of the years  
  Finds, and shall find, me unafraid.
  
  It matters not how strait the gate,  
  How charged with punishments the scroll.  
  I am the master of my fate:  
  I am the captain of my soul.

Own your shit.
