I don't know about any treatments as total replacement for therapy and/or meds (for me they are necessary) but I know for any mental illness exercise can help. It helps you feel good physically and mentally. Even just taking a walk everyday gets you out of the house and gives you something to do.

Yoga is good for you, it is healthy plus it teaches relaxation.

This past month I have been eating healthy and exercising regularly and it has helped me immensely. I just feel better overall.

Having a good routine also helps me, sleeping at the same time each day, etc.
