Meditation is a powerful tool for managing emotions and creating a sense of peace and equanimity through emotional highs and lows. I would highly recommend it for bipolar.
I recommend starting with repeating a #mantra. It’s easy and a good way to get started. After a few weeks, give breath meditation a try where you just focus on your breath. Start slow and try to work your way up to 20 minutes a day. Some people can do 20 minutes right away and others may start with only 2 minutes. Just feel what’s right for you and don’t put any expectations or pressure on yourself. Just try to be present and relaxed.
