Let me try again. I shouldn't have mentioned willpower. Let me restate the problem.

I try to do something and I have the physical sensation of hitting a wall that shouldn't be there. Thoughts never stop at that part of the brain.

I'm talking about a fundamentally different mechanism than thinking something is too hard. It's a hardware interruption that I have no control over.

I've spent my entire life working around this and it's difficult. Especially when everyone thinks I'm just being lazy or I just need to do this one thing. I'm still trying to figure out how to explain it better.
