Do these symptoms cause me struggle with my everyday life? Are things that normal people do all the time oddly difficult for me to complete?
If so, go get a diagnosis. Everyone struggles with procrastination to an extent, but if you try to sit down and try to start the work and just CANNOT emotionally bring yourself to do the work or get your brain to engage, then it's probably something more than just normal procrastination. If you are frustrated with your inability to remain focused and complete things on time that are just not inherently interesting to you, recognize that most people don't struggle like that. It's not a discipline problem it's an emotional regulation problem which is common of ADHD.
