Amazing, inspiring post. I too turned to meditation and walking to help my Bipolar, Anxiety and Depression. That and I started growing more plants than I new what to do with and selling some while keeping some for myself to keep for vegetables, which I will in turn harvest and donate seeds to my local Library seed banks and garden parks.
I'm glad to hear you have made a such a big change in your life for the better! Keep it up.
Also, I highly suggest you look into CBD oil if you have any pains from all the extra walking, it also helps anxiety. I have suggested the balm and oil to many people in my town and it has helped my local Natural food market a lot!
GOOD DAY SIR!
