I am not sure, in my experience, that it is a matter of will power . . . if getting over anxiety and depression were simply a matter of will power, I think many of us would not be suffering . . . .in my opinion, it takes a hell of a lot of will power to put up with anxiety and depression and manage it, so if all I had to do was say I could get rid of my anxiety simply by cleaning the house, I would have the cleanest house in the world . . .
For me, my house being a mess is more of a symptom of anxiety because it can be relentless and energy sapping . . .sometimes, though, and this depends on just our individual experiences and where we are with the anxiety, just a very very small accomplishment can lead to bigger ones . . .again, for me, this was a very long process rather than a light bulb turning on event . . . .and it had to be restarted I don't know how many times . . . .
So, please be careful of inflicting guilt on yourself but framing a messy house as a lack of will power because all that does is feed anxiety and depression but making you feel that you should be guilty and I don't feel that it is either productive or true . . . .
My two cents . . .take care, kc
