Thanks for the recommendations! I will investigate further. I'm amazed at how powerful these activities can be. And I'm glad that I gave them a chance. It is really easy to be dismissive of stuff like this. Having an open mind, giving them a chance, has made a world of difference for me.
Going through hard times, and seeing how fragile mental wellbeing can be, has given me a great appreciation for the work that these doctors are doing. I'm grateful you took the time to share.
