In Feb 2013 I had a breakdown which was quite a strange, difficult, and eye-opening experience.
If you are curious have listen to this podcast. It is on two episodes. The first one, posted on 18 July, is about the build up and coming out the other side. Here is the second one, which is the growth thereafter.
Link: My Breakdown and Out Again (part 2 of 2), also on Apple Podcasts. It is 14 minutes long with the lightbulb moment at 7:50.
