The most helpful thing I have ever found for dealing with my anxiety, which I definitely do get, sometimes, cripplingly, is good old-fashioned Buddhist breathing, Just breathing. Just focusing on my breath. Prayer also helps calm me down. I am not on any anxiety meds right now, so this does happen sometimes. I just have to breathe my way out of it. I have no other choice. It does work for me.

As far as general, overall strategies for dealing with mood issues and general Bipolar Coping With Life stuff, I love DBT. Use it every day, all day. Love me some Marsha Linehan. I also like CBT/REBT, Shame Resilience (the Brene Brown stuff--might be worth checking out her Ted talks), my faith, of course, regular exercise, regular old mindfulness practice, and other things. It is an all-hands-on-deck approach for me. I use it all.
