Sorry for your struggles. Not to speak to your specific experience but in evolutionary terms there are other ways to look at neurodivergence besides the challenges: https://complementarycognition.co.uk/

Hyperfocus for example can be highly beneficial if you manage to point it in the right direction, and in general neurodivergence tends to specialise either into explorers or exploiters, that is, those who are good at exploring the space of possible solutions, and those who are good at applying a specific solution to solve the problem at hand. Such skills can be problematic in isolation (as you've described), but in combination can be very powerful and could've therefore been instrumental to our past success as a species.

I understand this is not much comfort for an individual who is struggling, but I second the GP in saying that many modern societies are not setup to provide the best environment for the neurodivergent among us to thrive, to the detriment of everyone.

If you have the social support to cope with the costs of hyperfocus: forgetting to complete other tasks, losing track of broader priorities, and the risk of burnout.

Hyperfocus is dysregulation. It just looks productive to everyone so we trick ourselves into thinking it is a benefit. But it is stealing from your present (other tasks you are neglecting) or your future (burnout).

People who can manage their time can generally get the same work done in actually a similar span of time without the downsides. Take a bit longer maybe but then won’t have days of being distracted or exhausted or ill. Viewed over any longer span of time it is clear that hyperfocus is not really a benefit to the brain with ADHD.
