This may not seem logical and it is actually a paradox. But I have found it to be true in many areas.

My applying number 3 it will actually help you apply number 2.

I think you are not being totally fair with yourself with the word choosing. Like in I am choosing to not go for a walk. Maybe you are just not mentally capable of making that choice and carrying it out. That is classic depression. When I am in a deep depression I can choose and should myself to death but it doesn't change the fact that I just can't get out of bed and take a shower. The fact that I have 0 energy and 0 motivation. Of course I can in reality probably actually do it, but the amount of mental effort and anguish prevents me from even trying. So it is not much of a choice really, my brain is so whacked that it is damn near impossible. People without depression don't go through that. It is not my fault, it just is.

So paradoxically by accepting my disease and my limitations at the time it makes it much easier to implement step 2. I am able to do something about it. For me that means seeking professional help to get me to a place where I can take a walk. My implementing step 3 I rid myself of a tremendous amount of shame and it is freeing. Acceptance and surrender are powerful tools paradoxically. In simple terms it means I need help beyond my own means.
