Hi...I have found meditation to be helpful; I like guided meditation as opposed to just plain quiet time because I get too distracted without something to focus on.
I use the Total Wellness set of cd's by Belleruth Naparstek (I got them at amazon.com I think) and I also like the following site:
http://www.audiodharma.org/talks-gil.html It is a buddhist website, but even though I'm not buddhist, I have enjoyed Gil Fronsdal's talks. He has many subjects available to listen to, and I like to get one started and then just lie down on the couch and listen and try to do the deep breathing. It helps to increase my focus on something other than my depression or hypomania, and it helps relieve tension and anxiety.
If you find any other online meditation I'd love to know about them...I hope you will give it a try and see if it helps.
