I've been studying Buddhism and I've started using a mantra that says "we burn the embers of our earthly desires and they become the flame of enlightenment"
It works for me because I was abused and neglected as I child and much of my pain comes out of longing for what I don't or can't have and from feeling like my past PROVES that I am fundamentally defective.
RemindING myself that longing is common to everyone and that whatever my past I retain control of how this journey shapes me comforts me.
I also use "suffering is inescapable and shared by everything that lives"
And
"The divine exists in me as it exists in all things"
I feel less alone that way. As unique as my pain feels I know nothing is more common to all mankind than pain.
It kind of works for me right now.
I also use meditation. I have a very rich inner landscape peopled with various creatures I can converse with if neefed.
