Iām so sorry for your loss @Cosmic_Curiosity. 
Iām searching because we do have some things for grief & loss.
ā Grief & Loss Spell Jar
ā Farewell Ritual
ā Wiccan Prayer for the Departed
If I can think of any others, I will let you know. I know for me that writing a letter to the person from your heart & incorporating it into any spells or rituals for the grief & loss has been very helpful.
