As for what Apophenia said I was originally going to respond but forgot to hit the multiple quote button and my laptop was already dying at that point. I was going to mention that I do often walk around town or ride my bike, but as I said my laptop was cutting out. I'll check in on this one more time today before trying to go for a while.
You guys make it so tempting to forget this whole hiatus.
It is good to see you staying in communication with people, bi-polar can be fully hellish if you cut yourself off from others, especially the ones who do know personally what you are going through. A lama once said to me, "you can be happy in hell if you're smart !". And he was no fair weather sailor - Tibet got pretty tough - he was the same one who said to a group of us " we're teaching you how to pack a parachute. You may not ever need this parachute, but if you do, you better hope you packed it right." I'm glad I paid attention.
Walking and riding are the most regular kinds of exercise I do on a daily basis, and bike riding in particular is great for clearing the head. But the kind of exercise I'm talking about is another level up. When you fully exert yourself to the point of going outside your comfort zone, something happens...

The Brain on Cortisol Brain Leaders and Learners
Cortisol levels are crucial to manage. It is the substance in your body which feels like being on a dirty stimulant drug when stress levels get too high. As you know, depression is not just mental, it is a shocking physical sensation. Only people who suffer from it really get this. Intense exercise will immediately lower cortisol levels. That is such a relief when it happens. Also, your body will pump endorphins as a response to intense workouts. In other words, your body is a chemical factory, and the way you use your body and mind determines what kind of chemicals your body produces.
Resistance training, or any intense kind of workout, should only be done every second day. The body needs a 48 hour recovery period. Yoga can be done every day, although it is best to have at least one day per week when you fully rest.
Yoga also trains the body-mind with a relaxation response. The postures challenge you, and then while in the posture you consciously release yourself from the sense of strain. This teaches the whole system how to relax in a situation which would otherwise stress you, which may sound paradoxical, but it's true.
This information made life liveable for me when I put it into practice. You will also find it totally compatible with your beliefs and ritual practices.
If you want more info, please PM me. I am happy to tell you all I know, and help you design a program if you can't afford classes or a gym.
