If someone takes their own life in a family, it can have massive long term consquences within (and without) the family system. Teenage children may feel responsible, or fell divided loyalties, blame or shame.
A constellation will uncover the hidden dynamics and demonstrate powerfully that the consequences only belong where they should be - not with a loving child sibling or partner, who may feel they "deserve" to carry that burden even though it is not theirs to carry.
This episode my seem a bit harsh if this is close to home, but I urge you to persevere!!
