I feel your pain. Losing the guilt has been genuinely transformational. No more hiding and lying. No more making up excuses. No more trying at something, thinking this time it'll be different, only for the same thing to happen. No more of the resultant self loathing. I've been labelled lazy all my life and it always infuriated me, as I wasn't lazy didn't want to be. I just couldn't do the stuff. Like you, homework, uni work, then in my 'career'. Turns out it's not my fault. There were tears.
Anyway, see if you can get an assessment. Or, better still, delegate it happening to someone that doesn't procrastinate!
