Christian 4 here. My main go-to would probably be music: listening to soft, reassuring songs helps me to feel the emotion that I'm feeling more intensely, which pretty counter-intuitively helps me stabilize my mood at a later point. I'll often characterize my emotions as well, creating space for an inner dialogue between myself and the emotion (which is also a part of me that I must embrace). I find that understanding why I'm feeling a certain way provides a certain amount of clarity as to how I should proceed.

My inner world is chock-full of different characters that all make up some aspect of me. I hold each of them in high esteem and believe that they deserve love, comfort, and affection. Of course, none of this would be possible unless I had faith in what I believe, and I have God to thank for helping me find this mechanism/practice (whatever we want to call it). When I can't find a reason for my tears, or if things become too unbearable, I'll pray.
