It's more of an issue of organizing and properly prioritizing one's thoughts, along with the irl output being misaligned. This usually results in an incredible amount frustration that gets fed back into the thought loop and frequently causes confusion, which that confusion contributes to the above and can lead to depression and/or anxiety (both in my case unfortunately).

The struggle is more than the simplistic description of "this is not interesting. It bores me", it's really "my brain is uncomfortably overwhelmed with coordinating my thoughts with the tasks at hand to the point of feeling angry/anxious/down/<fill in negative emotion>, but oooo I could just cook a familiar recipe which won't require much thinking and can relieve me of, and potentially help with, this mental situation". It's complicated and requires a lot of "tricks" to deal with it. This is the case whether there are tasks to do, if one is just reflecting in thought, thinking up ideas, conversing, reading, etc... even writing this has taken me 10-15 minutes tbh...
