Thank you so much for taking a look at Plimsoll Line and giving such a good feedback! The anxiety caused by procrastination is definitely real, my wife and I both feel the stress when we see our devices spew the same reminders that have been postponed for many days (or months!).
The main thing that I would like the app to do is to nudge me to take small actions of visually surfacing the emotional impact of the individual items (a todo item or just a thought in my head) rather than them filling up my head. So I would like to be the one driving the app than the app driving me like most todo apps do. I want the app to help me break myself out of being paralyzed with anxiety by taking small actions that are doable and maybe even pleasant. Hopefully that makes sense when users try it. :)
So I'll have to think hard about how to solve the problems you mentioned, they are excellent points. Having fewer configurations and encouraging the user to take control of their emotions through small actions as core principles means some limitations in features...
Anyway, right now the app lets you write a "Quick Journal" into the Notes field in the Reminders app. I have in mind the app encouraging user to break down the items causing lots of stress into sub-items so it becomes more manageable. Or suggesting contacting a trusted friend that the user has selected in configuration beforehand.
Suggestions welcome on how else I can nudge myself and other anxious users! :)
