Ask HN: How do I move past and explain a 3-year gap due to mental health?

3 years ago I left the startup I co-founded due to the chaos, stress, and politicking (which I’m admittedly not good at), sending me into a deep dark place in the months following. I eventually came round to seeking help and have since worked diligently on improving my mental health, reconnecting with myself, defining my values and the type of people/work that align with them.

I’m just about ready to step back into the professional realm, but am having a hard time moving past spending 3 years not doing much work at all. Further, I have no idea how to position this for job hunting.

Any advice would be appreciated.
