That's so great @L-B .
I've read the research about the power of exercise for mental health. Well done!
Another thing is mindfulness. Have you ever used the Smiling Mind app? This is a free evidence-based app and it has different programs you can go through.
For me, the most helpful programs on the app are 'cravings' because I have intense cravings for junk food after I take my medication and it's not good for me; the "24 day sleep program" is also amazing, and "anxiety".
I'm interested to hear if you've ever tried it. I've also tried paid apps, but non have been as good at Smiling Mind.
