Integrate Shadow Self
In a low lit room light a candle (white or a light color is preferable), stand infront of it and look at your shadow
Look at your shadow and tell it,
"I bring my light not to remove you, but to see you, see your impulses be checked
I will listen to your pain
I put out my light now to see your darkness"
Blow out your candle and breathe in the darkness for a minute. Your shadow self could take many forms, mine came in as a child having an intense tantrum. Just be present with it. If you feel the need to say something to it, do so. Once you feel a sense of peace, leave the room (get a cup of tea or something if you feel called, it's a doosy).
After some time has passed, re-enter the room and re-light your candle. If you can bring more light into the room. Find your shadow again and say;
"I see you and I validate your pain
I choose to act from healed place
I refuse to pass this pain onto others"
Allow the candle to burn through. Follow up with a self-care ritual
