As someone recently diagnosed with depression I highly recommend this. It can be difficult to implement when there is a ton of stuff swirling up there but just start applying it to one thought at a time.

There will be days it won't work, thoughts and emotions overpower the rational mind too much, but there are also techniques to cope with this that MBSR teaches.

I am one to talk, all my training did jack today but dealing with love and loss is up there at the top of emotions and i'm dealing with it hard right now. MSBR is good to change your daily routine thinking though IMO.
