I use mindfulness. I am not as knowledgeable as I would like to be or as consistent at it as I should be. I usually always use some of the techniques with anxiety. I was taught to embrace the feelings that cause discomfort no matter of the past, present, or future. That is kinda' the purpose of mindfulness I learned. To recognize those feelings since they are the cause of discomfort and do it mindfully.
Mindfulness is having a large spurt of growth. There is much thought with it regarding therapeutic values. It is connected extensively with Acceptance - Commitment Therapy (ACT). There is a high success rate with depression, mood disorders, and anxiety disorders. A simple search at youtube offers a plethora of both practitioners and educational institutes. UCSD has center dedicated to it within its health system and curriculum.
I have friends who underwent workshop series provided by UCSD. Some were able to resolve past issues that prevented them from functioning in the present effectively leading toward the future. The ones I know have an apparent higher sense of happiness and calmer aura in stressful situations. I am thinking of committing to one of those workshops this year.
