Meditation where I live costs 10 dollars a session in a yoga studio. By myself I cannot do it. $10 a session is too expensive for me. When it was $7 a session, I went, but when they raised the price, I stopped. Exercise can be free but not necessarily so - from gym memberships to biking gear to yoga studio fees, it costs money. Perception is free. Diet changes - protein is expensive, and protein-rich diet seems to be beneficial for bipolar. Carbohydrates are much cheaper than protein. Think of pasta versus cold water fish (which is supposed to be especially good for bp).
