You admit to them. But that's not saying its all a conscious process, because its not. I recently admitted to feeling sadness. I never realised sadness for me was once so huge that it got tangled up with fear.

One morning I stood still, realised the monkeys in my head were beating me up in their attempt to avoid having to feel it. Once I said 'I feel sad', it was like pushing something huge out. Once it passed the fear just went. The sadness stopped being so unmanable.
