I would like to suggest that you're not lazy.
You're just dragging your heels because you refuse to do what needs to be done. Partially because it would mean that you have to give up some (most) of the ways you enjoy wasting time and partially because it will open you to a whole new level of rejection, dejection and depression.
Because you know that you will never always be good enough.
Because you know that you will never always know what you're doing.
Because you know that you will never get the kind of validation you need because it doesn't exist.
Because you know that you will start hating yourself more and despising your talent more and criticising your work more the more you create, especially the more you can't create.
And you hate that level of insecurity.
You hate that level of inconsistency.
Most of all you hate that you need to change, because change is scary, and unfamiliarity and fear is what makes you insecure.
And you hate that.
So you drag it out over the years, taking one tiny step at a time, always wondering why you never move.
But you have.
And you can't go back.
Yet you refuse to move forward.
So you rant and have panic attacks in the middle of the night, kicking against the establishment whilst complaining that no one supports you and no one understands, and everyone is not where they need to be in an effort to not have panic attacks in the middle of the night because everything is moving too quickly and you're not prepared to GO.
So you say you're lazy.
Because you don't know how to move.
