Any plans on adding search functionality, tagging, or categorization?

To test if this is your problem, look back at things that are difficult but didn't have a expectation or result riding on them. Say you created a small app or read up on a complex topic and understood it well. If you are able to do difficult things that don't have expectations but are not able to similarly difficult (or even easy things) that do have an expectation it is probably an issue of anxiety.
If this is your problem, I would recommend the book The Now Habit. Also, start mindfulness meditation if you can.
Hope this helps.
