Avoiding important things at work and then making up shit

Love to completely avoid a simple but critical task for weeks only to be reminded that I really need to have it done by now and now I have to make shit up and pretend I'm dumb or lost my notes or my dog ate my laptop, because saying "my brain didn't give a fuck about this particular task for the last month because there was no real deadline and now I'm filled to the brim with anxiety and I want to hide in my bed for three days because now there is one and it was today" is a valid thing in therapy but some how not at work.

Anyway, ADHD sucks and I get knocked down but i get up again and so on.
