I’ve been finding lately that when I find myself sinking into thoughts of stress, resentment, worry, sadness, or whatever, I can think to myself that it’s okay to feel these thoughts.  I don’t try to “should” them away.  Telling myself that I shouldn’t feel some thought is powerless.  But telling myself that it’s okay to feel that thought has power.  Being okay with feelings has the power to further remind myself that it’s my choice, and if I want to feel down, it’s okay.  It’s my choice.  It’s okay, and it’s my choice.  Somehow, at this point, the feeling fades away.  I’m surprised by the effectiveness of this technique.
