A Great post, excellently going over what happens when one procrastinates. and some common ways that help those who do procrastinate to potentially deal with the "overwhelm". What this post doesn't go over, though, is "executive dysfunction", which is an other form of procrastination that happens quite a fair bit.
For fear of making a comment no one will read, I shall copy paste a great explanation that really resonated with me, as a person with ADD and Executive Dysfunction.
"The prefrontal cortex is responsible for executive functions, like decision-making and impulse control. People with ADHD and other neurological disorders that affect the prefrontal cortex often experience difficulty making decisions and performing tasks, as well as exercising self restraint. Part of why people with ADHD tend to procrastinate so badly is out of genuine inability to begin tasks, even if they’re very important.
It feels, for me at least, like I’m constantly waiting for something and I can’t start X task because I’m waiting. I never know what exactly I’m waiting for, but that doesn’t stop me from wasting hours and days not doing the things I need to do, even if I have a desire to do them."
And while the same things done to help "overwhelm" Procrastination may work for Executive Dysfunction, many times it requires much greater help and often you can't be "talked into doing it", like someone can be talked down from being overwhelmed.
If you read this, thank you. Just wanted to spread the word.
