Then I spend about 30 minutes forcing myself to do whatever task until it no longer is forced.

Ok, HOW do you "force yourself"? I can do it for tightly aligned tasks, for a short period, but burn out rapidly. Back at university, I managed to induce heart arrhythmia pushing myself this way.

It also doesn't help with the initiator issue. HOW do you get yourself moving in the first place? I can reliably do it a couple of times a day, but day to day life needs more than that for basic maintenance.

Oh, and don't get me wrong, I'm functional, but it runs me at my mental limit all the time. Parenting pushed that to the next level. I'm permanently riding the knife edge of burnout.
