I realised that the dissociative response was due to a strong emotional response that I wasn't properly addressing. In my case there were a few causes:

- I severely lacked the organisational skills required to break down big work into smaller pieces so I got overwhelmed easy

- I had lacked confidence in things I was unfamiliar with like DIY or marketing

- sometimes I wasn't sure of the concrete next step and avoided the task instead of figuring it out

The way out for me was that through mindful meditation I learned to become aware of when I was checking out, and instead I would just think about what might be causing me strong emotions, usually the next thing I was supposed to be doing. Then I'd work through said emotion by solving the issue that was causing it.

Happy to elaborate via email if you want (in my profile).
