No, thats not the issue.

The issue is bottom-up-processing which starts at great detail at the bottom and not at low detail at the top. So basically I am not able to process things roughly but always pull out a huge hierarchy of dependencies (think of a Mindmap) when processing things. This is of course a very intense and draining process and if you go through this multiple times it causes heavy overload.

NT feature top down processing which does not cause this issue but is missing much detail in the process so it has its own disadvantages, but since 99% are NT the agreed upon methods to work through things is the NT way.

So in this context I meant if I am not focusing on just a small part, but want to keep the overview, damages me.

This is also a reason why big plannings are quite overwhelming and hazardous to me, since my brain works through it all during it.

Focus on a short time frame, one day at a time, possibly just the next short task.
