Experience them and breathe through them. It actually works.
I go through this dilemma repeatedly.. My T reminds me emotions can not kill me. Feel them, recognize them, let the pain roll through you like a wave and see what remains in its wake.
I breathe and center myself in the present moment. I feel the ground under my feet, the air on my skin, the subtle tension of my muscles. I listen to all the sounds around me. I isolate the different smells around me. And I remind myself that THIS moment is the real thing.

The past is gone. The future is unknown
All that's true is this moment that I am in, and in this moment I am OK.

I'm actually getting good at and avoiding all my unhealthy coping mechanisms
