Not a diagnosis, but sounds like depression.

Perhaps counter intuitively, exercise (get that heart rate up and sweat exercise) has always been the most effective for me. Managed my depression for ~25 years that way, such that I only have occasional (temporary) bouts of ennui.

I’d keep up with the touching grass too.

I bought one of their NVRs, so that currently stores recordings. I have yet to figure out how (or if) I want to integrate with my NAS or other (tbd) home automation.

I get push notifications on my phone and watch by having the Reolink app installed.

I went with this but PoE. Happy so far.
