I try to remind myself repeatedly to stay in the present. I focus on a saying that I read on a daily basis that keeps me in the present. When I'm hypo or manic I tend to think about all the things I want to do in the future, so staying in the present and focusing on slowing my breathing down seems to help.

One day at a time is enough...don't look back and grieve the past its gone...don't be troubled about the future it has not come yet...live in the present & make it so beautiful it will be worth remembering.

I would be interested in what you are doing to combat the depression?
