I've said it before, and I feel need to say it again. If you don't have time to read the whole thing please skip to the summary at the end.

There is anxiety, procrastination and task avoidance that everybody faces. Everybody has some things they don't like to or want to do.

However, what some people facing these issues often don't realize is that if it's happening (almost) everywhere, it could be something else. Are you struggling with a solid 50% of your tasks? Maybe even 100%?
That's not normal, I'm sorry to say (I'm in this boat myself for what it's worth). Don't feel bad, it's very likely not your fault.

Ask yourself - is my life significantly impaired by such procrastination issues? Are you missing important things because of your "tardiness"? (I have missed a funeral... simply because I forgot. Of course I didn't want to miss it.) Perhaps lost a job, or strained friendships/marriages because of your forgetfulness?

Do you struggle with long-term plans and their implementation? Perhaps have 1000s of unread emails and now no longer care, even though deep down you would have loved a zero-inbox?

Do you have more unfulfilled wishes, ambitious desires and crazy fantasies but struggle to live in the confines of reality? Justifying your inability to do amazing things because "you unfortunately live in the real world" and "neither does Bob"?

Well, it might be ADHD. Or autism. Or (C)PTSD. Or brain injury/trauma. Perhaps depression. Maybe generalized anxiety disorder, or OCD, or OCPD (note the extra letter). It could be a combination of those things, or perhaps neither. But if you felt some or many of those things to a strong extent, please read up more on executive dysfunction along with these conditions. Getting diagnosed, and treated - therapy, medications (esp for ADHD) - can be very helpful, to put it mildly.

An analogy I like to use is that everybody pees several times a day, but if you're peeing 30 times a day you should probably see a doctor.

Tldr/summary: A bunch of things can cause procrastination and anxiety/feeling bad etc like executive dysfunction ESPECIALLY if

a. You're procrastinating despite not wanting to, and probably feeling crappy about it

b. you also significantly struggle with time management/organization/long term planning and implementation(google its symptoms).

Executive dysfunction can be due to AD(H)D, autism, brain trauma/injury, PTSD etc, not just depression/"being lazy^+", so please read up online, get informed, and get an appointment with your GP/psychiatrist. And oh, go through this before you leave: https://comorbidityguidelines.org.au/img/appendices/appendix...

It's estimated that anywhere from 5 to 8 to 10% of the population has ADHD (and adult ADHD is very undiagnosed), so using the metrics of my last ADHD/health awareness post^ (which had 11 points), using the 1-9-90%^& internet rule about 110 people saw that post which statistically implies around 9 people with ADHD. You might be one of them, and understanding ADHD/whatever you're experiencing is generally life-changing for the better.
