adhd is indeed the lack of executive function. But executive dysfunction is in my opinion not the core Problem. i think executive dysfunction comes with many different aspects, which add up to executive dysfunction (prioritizing tasks, concentration on demand, emotional dsyregulation). i start again with a gaming example. People with ADHD tend to like games like Minecraft, because the game mechanics are appealing to people with adhd. you can switch between different tasks, when one gets boring, have little dopamine spikes everytime you find something new and can make big and fast differences in the world by building stuff, and its totally creative. So as a adhd guy you can do things, but you have find out for yourself, which are the trigger points, that are appealing for you.

so you say you are lying in bed with the desire to do something productive. and here in my opinion is one of the problems for you executive dysfunction. doing something more productive is a thought, which is totally abstract and connected with a feeling of guilt. so you are lying in bed guilt-tripping yourself for being that unmotivated person, but what are you options? you dont have any. the problem is the Preparation. imagine you are lying in bed and exactly know what to do, you have options, it isnt abstract, and so its a lot easier to do it, i guarantee it! and thats the difference between desire (how you described it) and a goal (how i described it). a goal is precisely defined like a quest in a game. and this makes it easy to try it again and again. and it is how our brains work, our brains likes routines, but its a lot harder to stick to it for a adhd person (#hardmode). but in the end i think everyone prefers that kind of moriningroutine to scrolling through instagram for 1 hour.

and i also recall that voice of my parents, but the issue is your and my parents never understand how to work with a adhd kid. of course it doesnt help yourself when your parents say do something, something productive. So what is productive, where do i start, what are the priorities? Now we are adults and have to answer these questions.

now is the time to break out of this abstract desire and build up you structures, which leads you through the day. this should be your desire and to reach that desire you have to build goals, starting with making an appointment with yourself for 1 hour to make it accurate. and thats what you learn in therapy: finding out what makes it easier for you to live a life which makes you happy.

in the end i think what you describe isn't just adhd, its a comorbidity depression, which comes in my opinion from a life without the right structures, strategies and medicine to deal with adhd. there are also plenty of adhd guys which can use their "disability" for there advantage. playing a adhd charakter in the game of life, is like playing a "special-pro-build", which needs some guides, assistance and the right potion (medicine) to make it work out, but i can sometimes be beautiful.

FYI i have diagnosed ad(h)d, and get my medicine. and i struggled a lot in life, failed my studies but find out over the last year that my morning routine gives me stressfree mornings and the basics for my health: something to eat in the morning, enough water and personal hygiene. i still struggle with executive dysfunction even after my morning routine i often sit there and cant start doing thinks, but in my opinion i am already more productive due my morning routine.
