I'm sorry you are experiencing this right now.
Normally if someone shares elevated anxiety/depression I will suggest increasing physical fitness, but I know you have that area covered. Another contributor to anxiety can be haphazard routine, so becoming a bit more consistent with daily/weekly schedules can help calm the mind. That is all I have for practical immediate solutions. Don't let mental health stigma prevent you from seeking professional help; nearly everyone needs some at one point in their life. Hope you get to feeling better soon.

This has me thinking about trying to find a map of belt and road participants, and a map of BRICS nations. Then overlaying all maps as a master map of anti western imperialism.
