First, thanks again for all your thoughts and words of love as I’ve been working through my mental health (see past post here). I continue to feel better, but have been very disconnected from work and taking long hikes and walks and talking with friends and taking medication so I should be getting better. I don’t know if I’ve stabilized, but I did begin to apply the scientific method to analyse my breakdown and share it with the world and if you are struggling with things there may be some interesting ideas in this long video.
