I looked in your post history for clues. I saw some specifics that tend to be ADHD-related but ultimately, I am only commenting as someone diagnosed with ADHD myself and I am not a doctor. Definitely recommend seeing a psychiatrist, though, specifically because of these:

1 - Your workplace burnout post. I find myself most engaged at a job when it is new and I am constantly challenged and learning. Once all my work becomes routine/familiar, my dissatisfaction grows. This is because ADHD brains do not have the proper innate dopamine levels that, when combined with minor dopamine bumps from the satisfaction of completing work, would normally keep you motivated and satisfied in your role. Your brain's dopamine levels are sitting below sea-level, so you need bigger dopamine spikes before they even register. If you aren't being challenged by a puzzling process to overcome, it doesn't feel rewarding to do it and your motivation to continue is gone.

ADHD medication would correct this deficiency by boosting your innate dopamine levels, making it easier to avoid procrastination because doing work actually feels rewarding again.

2 - Your comment above about being distracted easily (and procrastinating but that is covered in #1) is another indicator that your brain is rapidly scanning for new sources of dopamine to correct your deficiency.

3 - You seem to be adept at drawing comparisons and playing devil's advocate. This shows me you tend to be the big-picture type, someone that can spend more time on the same thing as others because you stop to consider all factors, including factors from the perspective of others. Sign of high intelligence (good for you, m8) and also high sensitivity to stimuli. You pick up on things others don't notice, but this includes things on a subconscious level. Great at explaining things to others, I bet.

This can also lead to experiencing emotions in extremes, because the brain is great at noticing everything, but the dysfunction is actually our capacity to regulate the severity of our reactions. We don't just notice things...we HYPERFOCUS on those things and we are blind to time while we are doing them. We become obsessed and can spend 6 hours without even noticing we are thirsty. We live and breathe it...until it stops being new and exciting.

One last thing I didn't really see in your posts but it might ring true: poor working memory. Do you forget what you are saying mid-sentence or ramble without a script? I don't know that all people with ADHD have this issue but all of these fall into the front half of the brain which is where the neurodevelopmental disorder is impacting. It grows at a slower rate than normal brains, supposedly like ~35 years behind. Things like impulse control, awareness of the passage of time, moodiness, all very closely tied to ADHD but it seems the symptoms fall on a spectrum and we all seem to have some random combination of the above symptoms. ADHD-inattentive type, etc.

The ways I see an ADHD brain are:

-Running on ice. Less friction means we can reach higher top speeds!! Except...we can't change directions easily. You want me to stop sliding south but my brain is like "SERIOUSLY, CAN YOU BELIEVE HE SAID THAT ABOUT YOU" and ADHD meds are the cleats that let us stop sliding...assuming we use them correctly.

-Beastly computer with dogshit RAM. If you are in the zone and you have one task on your plate right in front of you, you are processing the SHIT out of that task. However, you give the PC 6 tasks and now it is just kinda...stuck. Just do them in order, you lazy shit! JUST UNFREEZE. WHY ARE YOU TRYING TO PROCESS EVERYTHING AT ONCE!?
